im not getting spark in my car, and have checked everythign and am running out of ideas. i noticed my spark plug wires arent all the same length, and one seems to have a n extra bit of rubber on it, it could be normal but i wanted to check with you guys. they are y8 plug wires i believe (bought them a long time ago).



#1 has an extra bit of rubber on the end, and #1,2,3 are all the same length. #4 however is a bit longer, hard to tell with the pic, but believe me it is. is this normal? im only bringing this up becuase it seemed as if one of the plugs, the one with the extra rubber, didnt go all the way down when i push it in.

also are y8 and z6 plugs interchangable?

 

just get NGK wires with NGK spark plugs and get it over with

 

lol, theres nothing wrong with oem replacements, i only want ot drive the thing for now, but i need to know if thats normal?
