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 recommended 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.

Grear spark plugs, affordable.
Good product
Quick shipping! Arrived in one piece!
have lasted me a long time, considering that I use my STi for daily use.
Was driving the other day and my car suddenly acted like it was on launch control. It had been a while since changing plugs so that’s where we started and these did the trick and no longer have issues.
Fixed my misfire issue. Fairly easy install
They do what sparkplugs do and that's about all you could ask
Always great ordering from IIR. Shipping isnfast and quality is superior
It’s an easy replacement. But sucks at the same time. One thing I learned is to use you hands as much as you possibly can. These things are very fragile.
