They’re especially useful for performance engines or tight engine bays where heat buildup is common. Overall, they offer excellent protection and are a great investment for maintaining engine performance and durability. Plus the look good.

Got these for my Chevelle, has a 383 with long tube headers. These work perfectly. I drive it a 100 miles every week. No problems no melting, work and look great.

Tight fit. I am very happy with the way they look and fit

Beat the heat and get some of these

They look good wish they would have fit my corvettes L98..

I put angle plug headers on my small block with straight plugs. The wires were close, so I put these on standard 8mm wires. no issues at all, fit well.

Inexpensive, but still work/look good

I put these on brand new ac delco spark plugs and msd wires and when it was idling I could hear a spark ticking. The shield itself was arcing out on my header. How I don’t know but they sure are hurting my engine more than helping . I checked my wire and I can’t find anywhere where there is a break in it. How it’s helping to cause arc jump to my header is beyond me. But I removed the shield and I can’t get the wire to jump the arc
