MSD 3311 Silicone 90° Spark Plug Boots & Terminals

Why did you pick this product vs others?:Good

These are best I’ve seen

If you are replacing these you made a good choice.These are thick and hold up forever. They fit snug on plugs and these wire terminal is the best design around.Holds tight. Fits boot nicely. A little dielectric grease helps assembly and protects.

Great intructions and ease of installation. The sleeve is tough and thick for good support ensuring the cap is sealed . It's a little too thick and stiff that you can't really feel the click of the metal onto the plug end but you can eyeball it and ensure it's in. Worked excellent.

Tried two before this one, neither worked. This one is perfect! Like the old days when a product is what they say it is.Very pleased with this and hoghly recommend it.

The best quality spark plug boots I believe that you can find anywhere today I love the making the spark plug wire that goes in it and hooking it up to my Briggs & Stratton wmb motor was made in 1948. It looks awesome and I get lots of compliments compliments.

Had a situation where the turbo manifold was so close to #3 spark plug that it melted the rubber 90 degree boot and the spark voltage leaked to the manifold causing a misfire. Silicone has a much higher melting temp so will report later on how it lasts. So far so good.

Using this for the plug on my paramotor. Holds a lot better than the factory supplied on on the Nitro 200 however the small metal piece that is on top of the attachment point fell off. It would be a pain to reattach it so I've just been using it without that piece and it seems to hold fine.
