I've been ready these posts on different spark plugs and it got me thinking. I was looking at installing new plugs, since the ones that are in have been the same since I turboed my car.
For the last 3 years I have been using Champion "SRT4" plugs and it has been street tuned with HP Tuners @ 10psi boost. The car has over 30k miles the way it sits with no problems.

My question is : If I go to NGK LTR6IX-11 plugs do you think it will effect my tune to the point that I should have to alter it ?

Changing the plugs should not affect your tune.
