Product Description

- SPARK PLUG HORSEPOWER GAPPING CHART IS AT THE BOTTOM OF THIS PAGE- 
When it comes to performance, every aspect of the motor and setup plays a huge role in whether the vehicle will be reliable or if it will be plagued with issues. Sparks Plugs are one of the key factors in the motors overall health and ability to function. With that in mind we set out to once again, as we do with all of our HalferLand Performance Products, to find the best Performing Spark Plug we could, at a more affordable price then currently on the market. We have worked with manufactures from all over the industry and found NGK to be the best, tried and true methods to the plug. And are proud to announce our partnership with them.  To be sure you're Spark Plugs are set up to the best specification, please refer to our Spark Plug Gapping chart below. All of our plugs come with the standard OEM Honda Gap and will need to be gapped by the end customer for their particular HP and setup. Our spark plugs Heat Range is based off the NGK formula, the higher the number the colder the plug is (these are heat range 8,  stock heat is 6, that makes these -2 step colder) . NGK reputation, all the while with our cost coming in at more then 25% lower then most Iridium Spark Plugs on the market!!! 
(If you have a Stock or Bolt-on NA motor, please check out our "NA" Heat 6 Spark Plug in our "Tuning_ECU_Electronics" Category of the store for that listing)

Two Step Colder
I've been installing a super charger kit on my 03 Accord J30A4 for the passed few days. Havent quite finished yet but these spark plugs are certainly a needed part of the install. These were the only colder plugs i found being sold in a set of 6. I've been working with Halferland since October of last year. They got me programmed, flashed and in the tuning process.. it's been very satisfying. ..cant wait to get back to it once I'm done with this installation.

Installed into 500whp J32a3
Just went nitrous on my 06 TL. Ive installed tons of HalferLand parts (Block guards, stage 2 cams, 10k rpm valve springs, EGR plate and now speak plugs) and put about 12k on the car, I drive a lot. Pulled them to inspect before reviewing and they looked perfect even after 10+ bottle on nitrous already ran thrw them. Gunna buy a few more sets as spares
