Why NGK Iridium? More Durability and a Higher Melting Point compared to Platinum, better center electrode anti-oxidation and anti-erosion, improved ignition, superior anti-fouling, lower required voltage, new metal shell plating process for better anti-corrosion. One Step Colder plugs are reccomended for cars with heavy modifications. These NGK plugs will get your Turbo Subaru running smoother and free up some power through increased efficiency and increased heat resistance. These are available in stock heat or one step colder for cars running approximately 100 horsepower more than stock.
Please Note:Iridium plugs are able to use larger gap setting with less voltage. Some customers choose to regap these plugs to correct misfiring or tune for optimal spark -- do so at your own risk -- slide-type plug gapper will damage the fragile iridium tip.
This kit is for :
Subaru WRX 2006-2014
Subaru STi 2004-2021
Legacy GT 2005-2009

Great value
Installation is quick and easy, as it fits perfectly in the existing air filter housing without any modifications needed. The rigid panel design ensures a tight seal, preventing any unfiltered air from entering the engine.
In terms of performance, this air filter does a commendable job of filtering out dirt, debris, and other particles, aiding in better engine performance and fuel efficiency. It improves the overall air intake, allowing the engine to breathe easier and perform optimally.
