 |
 |
Why NGK Iridium? Increased 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, and a new metal shell plating process for better anti-corrosion. One Step Colder plugs are recommended for those Legacy GT owners with heavy modifications. These NGK plugs will get your Legacy running smoother and free up power through increased efficiency and heat resistance. NGK spark plugs are available in stock heat or one step colder for Legacy GT models running approximately 100 horsepower over stock. Please make sure you choose the correct NGK spark plugs for your Legacy GT below. |
FITMENT: 2005-2008 Subaru Legacy GT
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 -- using a slide-type plug gapper can damage the fragile iridium tip. Prices are for a set of four spark plugs |
