texaggie Posted March 11, 2011 Report Share Posted March 11, 2011 Just curious which spark plugs you guys are using, if you have changed them out, and why? Any information will be helpful and welcome. Link to comment Share on other sites More sharing options...
0201212 Posted March 11, 2011 Report Share Posted March 11, 2011 I swapped out to the ngk tr6 plugs. Gapped at .35 at the advice of my tuner. Hope that helps. I don't have a lot of mods just normal pulley, cai, and exhaust. Link to comment Share on other sites More sharing options...
texaggie Posted March 12, 2011 Author Report Share Posted March 12, 2011 thanks for the advice. any others out there? does it matter that i recently added the 2.5 pulley from VMP along with their tune? (love this set up and tune) Link to comment Share on other sites More sharing options...

0201212 Posted March 12, 2011 Report Share Posted March 12, 2011 If you check out Justin's forum on the VMP site he has a thread just for plugs. If I remember correctly he says that if you have 10,000 miles on the stock plugs and it has been driven like these cars were made to do then you might as well replace them. He has a lot of great information on his forum.I did my plugs when I installed the same mods as you. I used the VMP tune to get me to the Dyno so I could get it Dyno tuned. Hope that helps.

Slabo Posted March 12, 2011 Report Share Posted March 12, 2011 PM/email Justin. +1 I would ask Justin. I don't think you need to change until you get over 13 psi of boost. I am also running the TR6's gapped at .035 but I have a pullied TVS with other mods. Link to comment Share on other sites More sharing options...
JackC Posted March 18, 2011 Report Share Posted March 18, 2011 I have a tune from justin for 2.59 pulley and steeda cold air. with the factory plugs at high revs I would get a pop thru the exhaust. A friend told me my intake charge was hot well i emailed justin and he said if plugs had some mileage to chang them. So thats what I did went with tr6 gaped at .035 no more pop...my tune was a little rich So I put a bbk 65mm throttle body on and that made a big difference boost comes on quick. mods steeda cold air vmp 2.59 pulley bbk65mm throttle body steeda heat exchanger tr6 plugs gap .035 bassani race axle back Link to comment Share on other sites More sharing options...
lawdude Posted March 18, 2011 Report Share Posted March 18, 2011 I've had NGK TR6IX plugs for about 10k miles. Will be replacing them with identical plugs this weekend. Link to comment Share on other sites More sharing options...
