Put some new plugs in....

[DaveMan]

And WOW what a difference! I pulled NGK TR6s out and put in NGK TR6IXs. The car ran fine up until last week when it started to miss a bit at idle and low RPMs. The Iridium's fixed it completely though!

And I have to say, this car is SO easy to change plugs in! :rolling: :beer:

+1 did mine yesterday bro....real easy fix. the car idles better now too

 

[DaveMan]

I agree, car idles so much smoother.

I changed my TR6's out to TR7IX's and my tuner pulled them and put TR6's back in and said that Iridiums suck when it comes to making good or big power.

Hmmm. I always used iridium plugs with my Cobra. Never had a problem. Loved them.

my tuner did not recommend the iridiums, either. not a functionality issue, more of a cost/benefit issue. They recommend the $2/per BR7EF TR7

 

[DaveMan]

I don't feel like changing my plugs every oil change or anything like that so that's why I went with iridium plugs. I've used them in the past with me old boosted car and ran 22psi on them and they lasted a very long time.

I have run both...TR7 irridiums for the smoothest idle FTW! plus a colder heat range...anything to keep those cylinder temps down....

 

[HandoZiZle]

I have TR7IX's. It idled perfectly when i first got it but now after 3k on them, the idle is kinda crappy.

Can you just clean them with sandpaper?

Can't go wrong with the BR7EF's! I run them in my pullied Cobra and my brother runs them in his TT Cobra. I wanted to run the coldest heat range I could get away with to help keep detonation away. I live in a cooler climate and still no issues other than a VERY slight miss for the first few minutes after startup on a cold day. At the cost of them I don't have much reason to complain when changing them out every spring :rolling:
