I hate to point out the obvious man, but Coz is a SALES MAN, not a Z-Pro. He also sells a 300zx NASCAR body kit… that doesn’t mean it’s the best thing for our cars.
If you do search, you’ll find out that 90% of “Z-Pros” do NOT approve of iridium plugs in our cars. The other 10% will ONLY say they are benificial when used in conjunction with the HKS ignition or in NA Zs.
