GPI or any Aftermarket Wires, Do i need the Heat Sleeves? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hi, I had the Heat sleeves on my stock LS3 wires, I just put on a set of GPI Wires and I transferred the Sleeves, the Sleeves I believe made it really hard to get the wires to lock on the plugs as they would hit the header or bunch up on the head. They are on now And I hope I have all of them locked on the plugs it was hard to tell.

If I ever change plugs or have a issue can I leave the sleeves off? My Headers are ceramic coated.

Thanks

I've been running my car with TSP headers uncoated without heat sleeves for going on two years now and haven't any issues. I put on about 8k miles a year and had some cheap amazon wires on there but I just upgraded to TSP wires and still didn't put sleeves on. I think your fine without them especially with coated headers.

I have been running SP long tubes for 9 years now, uncoated and Taylor "409" wires without heat sleeves as long. The Taylor boots seat nice and tight on the plug tip and don't move or rotate.

I don’t use the metal sleeves; however, I do use summit brand DEI sleeves. Overkill, but it’s cheap enough and it’s still easy to R&R the wires.

I have the DEI Sleeves, they were fine on the stock wires with the metal also, But they were getting in the way with GPI, I did get them on and I put about 100 Miles today and they seemed to stay put. I may take them off the next time I take the wires off for anything.

Depending on how you drive the car sleeves will be recommended. I abuse my car, heavy throttle for long durations. I have my headers wrapped in DEI heat wrap and high temp wires with heat sleeves and I have already burnt through a few.

Do note that high temperatures will affect your wires. Quick little physics lesson: heat increases a wire's resistance. In other words, as your engine bay gets hotter your wires will not be as effective, the hot wires will make it so that the flow of current will be slower from your coil pack to your spark plug.

I do not use the sleeves have 2 inch ARH headers using MSD plug wires no issues.
