I'd be willing to try this. Don't see why it wouldn't work.

Enjoy...

car had 155k....and not sure how the car was treated....new stock coils probably would have improved it close to that much as well - car dynoed really low...shoot LS4 range...ouch! There is a guy on here dont remember screen name..gray or silver monte....orange engine bay, he swapped his out already...

i also have a book that states that the truck coils are rumored to work better than the car ones never payed that much attention to it though but after the car ran sluggish one day and i cleaned a horribly corroded battery terminal i learned how important that spark enery is on these things it seriously felt like a bigger gain than both the intake and the cutout

is there a way to test coils to see which are better besides running them on the engine? the word is that the truck coils stay saturated better im not sure how you could test this though

I know the truck LS2 coils put out 120 milliamps and the LS1 coils only put out 40 milliamps. I bet we'd see better gas milage and performance from a coil swap. I may do this.

Well, I have my eyes on a complete set. I'll keep you all informed if I buy them and will test them for the LS4 crowd and report back with the results.

I have them on my car. I went to these due to running higher boost and to help avoid some misfires. Honestly, I really don't think a naturally aspirated LS4 would really benefit from the coils.

I wish that guy had used his dyno time to test out a TBS...
