Has anyone used these yet on the lt1's?

 

I asked this question awhile back ago and most people said don't use them but have heard lots of great things about them. I just don't think anyone is using them I think it is hear say. Could not hurt to try them out if you got the time to replace them if they don't run properly. Most part stores should swap them out if you keep your receipt. Then you are just out on time not money.

 

yea i heard the good stuff, and even saw horsepower tv's little thing on them a while ago in the ls1. i was just wondering if it would be worth it since i have an important drag race coming up and i need all the power i can get.

 

I really don't see anymore than 1 or 2 horsepower coming out of this. You will see more power by running royal purple oil that the plugs. I picked up 3 rwhp and 5 rwtq just by switching over to royal purple. You may get 1 or 2 with the plugs but mostly better mpg.

 

yea i was fig. that much but just wanted to see if anyone ran them.

 

Waste of money and way over priced. Don't expect any parts store to take back a used electronics part either.

This just doesn't work. You have to change the ignition system to really do anything. Coils have dwell time, but very low spark time. They make it sound like a big capacitor that takes all the charge from your coil and fires it faster. Can't do this without affecting the timing of the engine. I would bet any mpg increases you could messure from these could be found in running 1 step hotter plug off the shelf.

 

My local autozone took back my autolite 104's and my O2 sensors. Had a bogging problem due to the need for O2 extension harness instead of splicing and soldering.

I am getting ready to run NGK BR7EF after I get my new parts in the sig.
