Hi every body i have a little question, i did a search and nothing came up that could answer my question, so here goes. My friend has a Stock EP3 that he recently supercharged with a JRSC, and we were wondering what plugs should he use, should they be the stock plugs which i believe he said they have heat range of 6, or should he use something different. Basically im looking for some part numbers for other people with the same set up, he also would like to stay with a NGK plug, Thank you in advance

 

try sending an IM to amf racing. he had a charged ep before

 

thanks i gave him a IM

anyone else have any suggestions

 

I had a JRSC on my K20A3 and ran the stock plugs with no problems, but it was tuned with K-Pro and that may make a difference.

 

You should run plugs that are one step colder. Your local auto parts store should have em

 

running stock plugs here....

 

im not to fiamilar with the colder or hater range, 1 step colder does that mean instead of running a 6 i would run a 7, can some one pls clear this up for me thanks

 

7 would be colder than 6

 

thank you
