I had a Softronic tune done to my car in 2012 and I have never had an issue. She drives like a champ. No CEL's. At the time I had the tune done I also changed my spark plugs to the cooler Denso IKH-22's. I put about 4000 miles a year on my car. The last time I changed my plugs was at the 9500 mile mark. The car has approximately 17,000 miles on her at this time. When is a good time to change the plugs again? Would the 20,000 mile mark be the time? I only ask because Spring is finally coming and I'm taking my car in for its 4 year service, oil change etc. I didn't know if the cooler plugs have the same life span as the OEM plugs. The only thing I hate about changing the plugs is that the labor is so much and you have to practically take off the entire back end to get to them.

I meant to post on the 997 TT board. But if anyone here has any thoughts or suggestions please let me know.

tuned turbos eat plugs. change em to the bosch gt2 oem. 1 step colder than stock. should be same for 997t?
...oh.. but probably NOT for the 997.2t. though i'd still run the oem gt2 plug. if i were you.

Thanks for the advice. I will take note of this.

glad i could help. plugs n coils, plugs n coils. it should be a mantra for our tuned cars. you can have shyte plugs at 7500 mies for hving done nothing other than push the car as intended! coils can crack and you''d never even know it ( but the car will ).

speaking of cars.. some of ( ahem ) "us" have a bit of 997t envy lol and yours seems to be a prime example of "why". driver her in good health! cheers..

Thanks for the compliments. If I ever think about selling her I'll call upon you first.
