New spark plugs, more power

[firefighter3931]

Forgot to mention:  I am running a one-off CompCams hyd roller cam with these specs" Gross valve lift Intake .596  Exh .577  duration @ .006 tappet lift is 304 for intake & exh.   valve timing a .050  Open Int 14 BTDC  Exh 54 BBDC   Close  Int. 54 ABDC   Exh 14 ATDC

Cam specs for cam installed @ 110.00 intake center line

Duration @ 050  Intake 248   Exh 248 
Lobe lift both  .3800
Lobe separation  110.0

The shop installed Champion RN12YC in it and that is what is still there.

I'd give a set of these a try and see how it runs

Ok,  I will put them in and give it a try.  Thanks and I will let you know how it works out!

P.S.   My local O'reilly's has this plug for $2.19 each and they are in stock!

I finally got a free evening to swap the plugs! Thanks for the suggestion Ron and for the link to the inexpensive website Cudaken! 
I haven't taken it for a drive yet but intend to tomorrow evening.  Here is a picture of the Bosch platinum plugs that I did have installed. This is the first time I have seen this....the electrodes are half tan and half dark in each plug  .

Maybe the side that faces the intake valve gets washed by fuel vapor.  It would be hard to prove unless you made a mark on the spark plug to keep track of its position.

Hmmm... that is a good idea.

I took her out for a test drive and it is a great improvement according to the butt dyno! THANKS RON!!!!

I took mine out last night it ran great.

I STILL can't believe how effective these plugs are.  I feel and sound like someone trapped in an infomercial for something that couldn't possibly work, but suddenly IT DOES...

That sums it up perfectly!  I think I will have to look for some for my SRT4 to try....

It's nice to hear all these cars are showing some driveability improvements and performance gains 


Makes the hobby a lot more enjoyable allthough the back tires might not be so happy !
