You know I've gotten changing the plugs down to like 20 minutes on my car but.................................

Who put the spikes on the coil pack brackets??? Why?

I take the passenger side off to take the plugs in/out but I have to have the pack in there and attach the wires and every single time I get scraped to hell on my left arm.

 

I took a 3" cutoff wheel to mine. That actually made them worse. I rounded them off after that.

 

I was wondering the same thing cuz those things are a PITA First time I did em it was actually pretty quick but the second time I had hell with the passenger side an scraped the s#!t out of my hands and arms, (those things are pointless if you ask me) so I took off the brackets, too. Alot easier

 

I believe they are there to hold on the fuel rail covers that are on the Vettes.

 

To make you take it to a dealer for a plug change duh...lol

 

It only takes ~1 minute each side to take the coil packs off, I started doing that rather than suffering the wrath of the coil spikes

 

prolly a disgruntled lt1 owner...wanted ls1 people to suffer at least a little in the absence of optispark

 

LOL, best and most plausible answer right here.

 

They are indeed for fuel covers. They work quit well at laying a hand open though!!!
