 Please Contact Us at [email protected] to receive our shipping/Core return address. If you have any questions in regards to which Top Plate cover to buy, please don't hesitate to contact us at [email protected]

Please note, if you choose to add in the Intake Manifold and cover, our pricing covers not only the cost of the Intake Manifold, but also the Top Plate/cover AND the full Port and Polish service.

Here we can either provide the IM for you and Full PnP OR you can send yours in for full PnP service. 


Honda/Acura J-Series - Intake Manifold Porting and Polishing Service

Applications  
* We can perform the service on any Honda/Acura Manifold, along with other manufactuers. If you would like the service for another manufactuerer, please contact first to discuss options. 



Potential HP Gains
5-25 whp (Average seen is 10-20whp)

* Gains will vary greatly due to many factors such as engine health, other modifications, weather conditions, if you setup is NA (suggest Stage 1-2), Forced Induction (Suggest Stage 3) or Nitrous (Stage 3) etc. These numbers are estimates and not guaranteed. Our proven dyno numbers can be seen within the product photo's with our J32a3 NA on 93 pump gas and our HLP stage 2 PnP on the IM, HLP PnP runners and HLP Venturi PnP TB's


HLP CERAMIC ENAMEL FINISH
THE SECOND LISTING PHOTO SHOWS A THERMAL IMAGE OF HOW WELL OUR HLP CERAMIC ENAMLE FINISH WORKS AND WHY WE HIGHLY SUGGEST THE AFFORDABLE FINISH FOR ALL ALUMINUM AND MAGNESIUM INTAKES. THE LOWER YOU CAN GET THE INTAKE TEMPS, THE DENSER THE AIR WILL BE AND THE MORE POWER YOU WILL MAKE. THIS IS HOW WE PROCUDE THE RESULTS WE DO WITH ALL OF OUR BUILDS...OPTIMIZING EVERYTHING DOWN THE ENTIRE LINE AND THROUGH THE ENGINE


* Please note the Stage 1-3 options in the "Options Drop Down" located above, near the pricing. You may determine the level of PnP work you desire. If you have any questions, please don't hesitate to ask  [email protected] *

Our HalferLand Performance Ported and Polished Intake Manifolds are the perfect addition to your bolt-on J-Series! If opting for this service, we HIGHLY RECOMMEND having your runners done at the same time, as we gasket/port match the Intake Manifold "Runner Side Ports" to the "Inlets of the Runners" themselves. That matching achieves the best possible air flow through your entire intake tract.
  Our "HP" Intake Manifolds are meticulously port matched, opened to the maximum diameter (TB Inlet and Runner Side Port outlets), while still maintaining structural integrity, air velocity (which everyone else sacrifices) and also smoothed/polished to a high shine (Stage 2-3).  In order to take advantage of your other bolt on modifications (Intake, EX, etc) you must also make sure the engine is taking in, or can take in all the air it requires. This approach is what has yielded our motors the amazing NA (316whp/262wtq J32a3 on 93pump) and Boosted Power (560-580whp on only 8psi J32a3) that other companies struggle to achieve. It's only when each part is maximized and matched down the entire intake track are you fully taking advantage of the work and gains. On top of this, you'll find our quality and pricing is unmatched!! With the amount of love and precision put into all of our parts, you will not find a rivaled part with this quality, for this price. 



DIFFERENCE BETWEEN STAGES 
 YES, THERE ARE INDEED STAGES UNLIKE WHAT OTHERS HAVE SAID.....WE ASSUME TO VALIDATE THEIR PRICES OR JUST ZERO REAL WORLD TESTING, WE DONT PORT AND POLISH CHEVY, FORDS, ETC..... ALL WE DO IS HONDA/ACURA J-SERIES ENGINES)

STAGE 1 SERVICE 
Our HLP Stage 1 Service is a "Port Only" and NO Polish service that leaves a slightly rough texture to the intake ports. The Manifold Inlet will be opened up to the appropriate size for your application or TB being used, and the outlet ports (runner side) will be opened and port matched to the runner gasket size opening. This is recommended to the bolt on & daily driver customer that want more power around town. This will maintain low end torque and help increase mid to top end power.

STAGE 2 PNP SERVICE
Our HLP Stage 2 PnP Service will encompass all of stage 1, however more of the turn radius will be addressed, along with a full high shine polish applied to the manifold inlet port (TB side) and all of the 6 runner side outlets. The high shine/smooth finish will aid in air velocity, cutting down on turbulence, slightly improving air speed through the vital parts of the manifold, being the initial inlet transition and final outlet transitions. This is best for the NA, daily, full bolt on, larger TB, Street/Strip customer that wants to target the most Mid and Top End power 

STAGE 3 PNP SERVICE
Our Stage 3 PnP Service is what most all other companies offer and claim is the ONLY WAY to PnP a manifold, which 100% is not true. This stage will encompass all of the Stage 1 and 2 service but we will also port and polish the entire interior of the manifold. Why we know this is not always suited for NA street builds... well testing for over 15yrs (2008) in multiple real world setups (3.0, 3.2, 3.5, NA, Nitrous, Turbo etc). When porting and polishing the full interior of the manifold you are increasing the overall volume of the interior passages, thus slowing the air down. Unless a power adder such as nitrous or forced induction is added to account for the loss in velocity and extra volume, the air stream is slowed, as there is now more internal volume that must be filled before entering the cylinders. 
WHERE THIS IS BENEFICAL...as mentioned if you have or will have a power adder setup such as nitrous which expands into the manifold or forced induction which shoves air in past atmospheric density, will make up for that loss in velocity and can actually benefit from the larger volume of air now allowed into the manifold. We suggest our Stage 3 PnP for any power adder vehicle such as Nitrous, Turbo or Supercharger.



* RETURNS & ORDER CANCELING POLICY*

- ALL ORDERS ARE SUBJECTED TO OUR (1) MONTH (28 DAYS) RETURN POLICY (THIS EXCLUDES ANY PORT AND POLISH PARTS, PNP PART RETURNS/CANCELLING IS BELOW). WE OFFER A NO HASSLE RETURN POLICY ON ANY PARTS WITHIN THE FIRST (28) DAYS OF YOUR PURCHASE. ALL PARTS MUST BE RETURNED IN THEIR ORIGINAL CONDITION, PACKAGING AND NEVER INSTALLED. A FULL INSPECTION WILL BE PERFORMED UPON RECEIVING THE ORDER/PARTS BACK TO US AND IF DETERMINED THE PART WAS INSTALLED OR MODIFIED/DAMAGED THE RETURN WILL BE DENIED. 
ALL REFUNDS AND RETURNS ARE SUBJECT TO A 3.5% CREDIT CARD TRANSACTION FEE. THIS IS DUE TO THE INITAL ORDER TRANSACTION FEE WE WERE CHARGED FOR YOUR ORDER, PLUS THE ADDITONAL REFUND TRANSACTION. THOUGH THERE ARE TWO TRANSACTION FEE'S CHARGED TO US, WE ARE ONLY CHARGING YOU FOR THE REFUND FEE.
- ANY PART RETURNED AFTER THE (28) DAY RETURN POLICY WILL BE SUBJECTED TO A 3% RESTOCKING FEE. 
- FOR TUNING ORDERS, NO RETURNS ARE ACCEPTED UNLESS NO TUNING OR REVISIONS HAVE BEEN STARTED. AFTER OUR FIRST REVISION/TUNE IS SENT TO OUR CUSTOMER VIA EMAIL, NO REFUNDS WILL BE ALLOWED OR AUTHORIZED. THIS APPLIES FOR BOTH SINGLE SESSION (TUNE TILL RIGHT) AND LIFETIME TUNES.

- There are no returns accepted for any Port and Polish parts, due to the parts being modified and unable to be returned to their stock/original condition. There is no exception to this policy...EVER.

- If the customer selected to have HalferLand Performance source/provide a core part(s) and chooses to cancel their order prior to shipping or starting the modifications/porting, a 20% part cost restocking/sourcing fee will be assessed from the credit/return. Example, the core part provided cost $100, a 20% Restock/Sourcing fee of $20 will be deducted from the credit of the order. This is due to our cost to source, purchase, clean the part and now the order being cancelled, we now are forced to sit on the part with direct order being associated with it or that we can use it for. 

- Order Cancelling may be done prior to the start of any modification or work and before shipping. If the parts modifications has already been begun or the parts has shipped, then the order cannot be canceled and will be filled/finished accordingly. If its a non PnP part and the order ships, the customer is responsible for returning the part/order using their preferred carrier. Our (28) Day Return Policy guidelines remain, parts must be returned in original packaging, never installed, modified or damaged

Stage 2 PnP
Have to say Im very impressed. Got the stage 2 pnp on a stock ecu, took about a full tank of gas for the ecu to adjust but slowly but surely i felt more and more power each day. Mid range and top end are vastly improved!! Highly recommend

im happy with everything except for the fact that they put a sticker on top of the butterfly valve and it peeled off the paint on top of it other than that everything else looks great. ****HALFERLAND CUSTOMER SERVICE RESPONSE **** - Hi Tim, we apologize for any inconveniences. As other companies we mark or identify our products with our logo stickers. They are applied fresh after painting and baked along with the paint to cure it. This ensures the logo sticker doesn't start to peel. We assume you peeled it off, being you said it removed paint. As mentioned they are baked together. If you would like the top plate re finished, please email our customer support ([email protected]) and we will be more than happy to assist you

Like art
My intake manifold came out extremely nice with their gold nugget finish. It also brought the IAT's way down by about 30° which is hard to believe and their PnP service is incredible. Top end is just nasty now. Thanks

A must have
I feel this is a must. I went with the stage 2 because I'm still mainly street driving but overall the power is better but definitely mid and top end. Do you email me the coupon code for making my review or how does that work? ~~~~~~~HLP CUSTOMER SUPPORT RESPONSE ~~~~~~ Hi Lane, thank you for your support and review.

Overall good experience
It took them about a week to source a J35 magnesium manifold for me but once they did the part was done in 4 days. The manifold is very nice, very light and the ceramic finish looks great too - HLP CUSTOMER SERVICE REPLY - Hey Zander, we see you left a 4 star review and we assume its not a 5 star due to the week sourcing delay? We greatly apologize for this. As everyone and especially during the Black Friday sale when you purchased, we really got backed up and didn't realize our inventory was off for our IM's...running out when we got to your order. We noticed and got them on order immediately but shipping did take some time. We are happy to hear you like the IM and we ask you email our customer support so we can provide you with a little "Thank you" gift and to apologize for the slight delay with sourcing your IM. We would hope you change the review to 5 star but that's of course 100% up to you.

Immaculate Stage 3 Magnesium Manifold
Purchased their J35 Magnesium Manifold with the Stage 3 PnP on it, matched to their new 79mm throttle body and its an absolute piece of art. I'm not new to the tuning scene and opened the manifold to see the work and its next level. The port matching to the oem mls gasket was spot on and the HLP 79mm throttle body looks incredible matched to the IM with the cover finish in their gloss black. I will definitely be back for their ported runners.
