My friend works for a parts store, he gets 25% off any fuel injectors, cam sensors, oxygen senors spark plugs, EGR valve, IAC valve,etc...and he will sell them for 20% off to try to make a quick buck. I bought spark plugs that were $65 at pep boys for like $50 from him. The name of the company is called STANDARD, they make OEM products, high quality. And the spark plugs he has are NGK Laser Platinum. I have 100% feedback on ebay, e46fanatics, clubrsx, mustangforum, etc.... Message me if you need anything
