Anyone bought any of these things? I got a set off of ebay (greg b or jersey devil i think) a while back and they are copper colored, not silver like all the pictures. I tried to measure the difference in resistance between them and the stockers with an ohm meter and didn't see any difference. Was this a waste of money?
I switched my booty springs and coil springs.... with some from greg b... the springs I got were silver like his pictures.... I never thought of measuring the resistance though... Rksport who makes their spark plug inserts out of the same metal claims they are 80% less resistant then oem
At a given voltage, the current is proportional to the impedance. Voltage = Amperage x Resistance.
Unless your running boost or nitrous, I suspect that the benefits are negligible. I bought them anyway though.
btw, if you are going to buy them, nice plugs and the upgraded coil springs would form kind of a package.
There's too much blood in my caffeine stream.
I'm running the ngk iridium plugs. Wonder why my springs are not silver?
well i made some for afew people just copper no silver but i have both the best is the copper with the silver coating and by the way i now make both for the 2.3 2.4 u have the ones in the booty and u have 4 springs in the top coil packs for the price of this little mod u cant go wrong.......8.00 for the set shipped is my new price that is 4 springs for the top and 4 springs for the booty inserts......or u can go pay 30.00 at rksport thanks alot .........
and at rksport u wont find the 2.3 2.4 upper coil inserts cause no one makes them just me by the way and think at it like this evey little mod comes together for the price of some mcdonalds grub well u get the point lol thanks alot i have had tons of positive feedback on them hell i only sell them for 5.00 plus 1.00 for just the booty set i make hardly anything on these........packaing material bags my time ......just have a bunch will continue to sell till they are gone i dont even own a cavy no more but alwways come back on here......figured i make springs on my cnc for a living so years ago i thought i help peeps out instead of the rip off price of 30.00 from rksport i dropped way down for u guys..............

Thanks, you didn't have to do that. That is excellent service indeed.
Sweet car by the way...
just a FYI here are the 4 coils you can replace in the coil pack... for the price its a nice upgrade... plus I was swapping idi covers / plugs anyways...
and here's what the upgrade springs look like...
I got rid of my setup like that years ago.
But Greg B is a great seller and can be trusted in what he sells.
Heck, he's been around for a long time so he's doing good to help out the J-body community wth this.
Good luck with it.

thanks alot man u have bought alot of goodies from me in the past .......
I've had the RK ones for probably five years now. Didnt really notice any difference performance wise. But when we measured the resistance there was a definite difference.
