Design Engineering 010544 Titanium Protector Review

This is a premium quality product. Thick, durable fabric. They replaced a cheaper eBay version which was generic and let me down. Have fun shopping!

DEI bought because they have to be good quality. This. Spring. You didn't do the job. less than 500 miles without directly touching the manifold and ruined a new set of spark plug wires.

The insulators are well made but not suitable for my application. A rigid ring sewn into the end of the insulator must pass between the shoe and the head. The ring did not allow the cap to fit properly on the spark plug. Ring ID is less than Boot.

These boots work fantastic I have two header pipes that are so close to the spark plugs that the boot hits the header pipe and doesn't ignite, well worth it costs!

My ACDelco cables already came with a metal shield, but I wanted something different for easier removal later. These fit and work great. They even cover half of the cable as well as the trunk. They are excellent quality and larger than expected.

I installed and did not add the headers on my 2009 Cadillac CTS-V. After about 10-12 thousand km I felt a slight dead center idling and under load at low revs with hard acceleration. These worked great! Because the standard plug leads (which I used) are so short, they gave me almost 100% coverage from boot to coil pack. I've only driven about 2000 km with it, but absolutely no problems.

Now I have these V8 kits which are 6" long for my 2008 Corvette Z06 LS7 427 engine and 8" long for my Silverado Bought in 2004. SS 6.0 L with Kooks distributors. They work great and don't come apart like the cheaper imitations I've bought here before. I bought both DEI sets from Summit Racing. Both orders arrived within 2 days at the best price with no shipping, taxes or restocking fees. Very satisfied.
