- Please note, You can now either choose for us to provide you with a Used IM to be serviced (Core Program) or you may ship in your own Manifold so we can perform our porting services (Service Only Program)
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. This is not like other companies $600 stock IM listing, where you're buying just the stock Intake Manifold with no PnP. 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
* 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 after Tuning
* All expected gains vary greatly and are highly dependent on your engine setup, supporting mods, fuel type and compression ratio. Heat soak also play a major role in power, which is why we highly suggest our HLP High Temp IAT Reducing Finish *
Stage 1 - Average seen is 8-10 whp NA
Stage 2 - Average seen is 10-20 whp NA
Stage 3 - 15-25whp forced Induction/nitrous with our Stage 3.
~See below stage suggestions~
* Gains will vary greatly due to many factors such as engine health, other supporting modifications, weather conditions while at the dyno, if your 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.
