Product Description
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 design, at a more affordable price then currently on the market. We have worked with the manufacture from the ground up applying tried and true methods to the plug such as our Tapered Platinum Strap, Fine Wire Iridium Electrode and High Temp Ceramic Insulator body. 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 (Including these Stock Heat Plugs) come PRE-GAPPED with the standard OEM Honda Gap of .030". If you're using these for a higher HP NA motor (300whp+) the plug 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 6, stock heat is 6, If Heat 8 that would be -2 steps colder)..... NGK is a tried and true spark plug, so we used the same general theme of their plug, adding in our subtle yet effective improvements (IE. Our Iridium Strap), all the while our cost coming in at more then 25% lower then most Iridium Spark Plugs on the market!!!
(If you have a Boosted motor, please check out our "-2 Step Colder Ultra Performance" Heat 8 Spark Plug in our "Tuning_ECU_Electronics" Category of the store for that listing)

(These specs will vary, it's best to consult with your engine builder if unsure about your situation!!!). These specs are in place to guide you as a general rule of thumb and is NOT the "Rule All" specs. We are not liable for any mishaps from our data being used. General Rule is if you're getting Spark Blow Out, you need to gap down your plugs as the air is blowing the spark out.
