Spark plug thermal insulators..
Years ago I bought which at the time,was a good set of thermal insulators for my plugs since I'm running headers
My plug wires are 90 degree bend on both ends and for the life of me could not get them to fit over the boot...
Mr Gasket makes a set # 11077 which I saw in a you tube video fit easily over a 90 degree boot..Thing is they are 19 dollars a pair...
Anyone know of a good set that will fit over a 90 degree angle?

Check out Summit Racing. Here is a tip. As you know, the jackets are on the pricey side and are usually sold in packs of four. I have found Moroso insulator to be excellent quality but a bit too long, maybe 8-9". So I cut mine in half and got eight pieces out of the deal. There is a steel ring inside that I removed and did not need.
I too have 90* bend MSD plug wire terminals. The Moroso jacket slip over easily. They can be seen on my profile, engine build photo album.
There they are

zrc- check out the ceramic plug wire sets from Accel. I have two spark plug connectors that are close to my headers and have fried all of the slip over insulators made of fiberglass and the other heat resistant materials and once the insulator is gone, then the silicone spark plug insulator also gets destroyed. The ceramic ones are virtually indestructible. They come in straight, 90 degree and 135 degree spark plug ends. They also are available as a complete set or you can buy them one at a time. JEGS has them for about $120 per set or about $20 individually. You may need to call their customer service to get the part number for the individual ones. Only one disadvantage. The boot grips the spark plug in a death grip and you risk pulling the wire out of the boot, so use some silicone high temperature grease when you connect the boot to the spark plug. Because the boot is ceramic, you cannot strip the wire and fix it like a flexible rubber boot.
