I am about to get my car dynotuned on monday after my recent cam install. I have been running TR6's for nitrous. Now I sold the nitrous and installed a Comp 232/236 595/601 on a 112+2. I took the tr6's out and installed the stock delco iridiums. I am wondering if the stock plugs are too hot. What plug would you recomend that I run for the dynotune-TR6,TR55, or keep the Iridiums. Thanks

 

I run the TR55's and love um. If you already bought the delco's then just use them. For all motor they wont be too hot in my opinion. Dont spray with them though..

 

Help Please
