Precision Raceworks Coil pack review

Well i got a set of these and after installing these and doing the new coilpack flash I can finally say WOW

What a huge difference in smoothness and power delivery.

And yes it can be made to fit so it cant be seen

Doing some dyno and drag strip testing weather permitting this week

I can agree with your thoughts on the coil pack Marty having been in your car through its metamorphosis. Impressively smooth and even.

I set will certainly find their way onto my chariot.

Are you going to run a bigger spark plug gap?

So after numerous runs on the dyno and pushing the absolute limits of 98 or
at least i though where the limits and where normally the engine would missfire
it just keeps going

This is a long term test but it looks promising

ngk 5992 one step colder with a gap of .024 as I'm only running 21psi and pretty much
anything over that will kill my turbos quickly.

These have been on the car for over a month or so now and having no issues.

Car starts perfectly and first go even on the coldest of mornings, no misfires or grumpy
cold attitude from the engine even when the car has been sitting around.

I'm going to hard wire these eventually permanently and make a few extra improvements to clean up the wiring.

The problem with pencil type coil packs they sit in the head and slowly cook especially during our summers, this should/will eliminate that problem.

The spark plus are now close to 10k old and show no problems with these coilpacks

So if you need new coil packs don't waste your time with the crappy stock stuff.
