Ok so i have noticed that my car has been missing at lower rpms and has a hard time starting up. Right now i have IK22's but i can't tell if they are the reason for this. I have a jrsc race kit installed. I pulled the plugs and looked at them and The "Porcelain" looks a redish color with the "base ring" black and the "ground strap" is a blackish. I think the pulgs have been in since the car was s/c about 8k ago. I have done alot of tuning so idk if i may have fouled the pulgs or what. Is there a guide to show me how they should look? I know i need to replace them but what should i go with? Ik22/24's, ngk? if so what kind. What should i get? thnanks

 

ttt.
