anyone?

 

Dont waste your money. There is no reason to replace the factory coil packs within the limits of these motors. Take a look around the Lightning world and you will see guys with 650hp+ running the stock ones because they are the most reliable. Alot of the 3v mustang guys jumped on those Granatelli ones when they first came out and had so many problems with them that they just turned around and got rid of them. You will also not gain 15hp as stated by them. Use the money towards something else.

 

i agree ^^^ stick with the stock ones, they work great.

 

They are worth changeing if you live in a very humid area and have a blower.The stockers put out 18,000v to the 40,000v of moto blue or 60,000v of the Granatelli's

 

how come the lightning guys pushing 600HP recemend using stock?

 

beats me, and I dont think the COP's on the L's are the same as the ones on our trucks, but I don't know they might be 60K just sounds better that 18K to me I guess

 

coilpacks themselves are the same but the boots are different. Trust me there is info all over the forums showing how there is no gain and in most cases just headaches. A friend of mine, Dave Beyer, whose '05 GT is making in excess of 800rwhp and is sponsored by Lethal Performance is using the stock COP's bc the Granatelli ones were causing tuning issues.
