I know stupid question but I have to ask. I am running the Stage 1 from Vishnu and so I boost to 23 psi. I have the stock plugs in. Would it be a good idea to change to a little cooler higher performance plug?


Thanks

Well thank you SGTZ, so in you opinion the Densos are the only way to go? Stay away from a step colder NGKs. I know that you get what you pay for but 4 NGK's(step colder)for 12 bucks and 48 for 4 Denso, is there really that much of a diff?

 

not sure....i opted to go with the Denso's...but the stock are NGK..so i really dont think that you can go wrong either way. it is up to you. i am sure that they offer similar performance. if NGK sucked...i am sure that mitsu would not use them..Hope i could help
