Excellent
Lasts longer than the (Lifetime Guaranteed) ones from the zone! Well made and works like it should. I've used a lot of aftermarket caps. over the years, but with this flat top design, AC Delco, is the only way to go. I Highly recommend this distributor cap and the AC Delco rotor button as well.

Tough to get that rea screw in
The cap itself is fine. The struggle to get that rear screw started without dropping it into the abyss on a 4.3L V6 2007 Sierra is real. How much harder would it have been to make that a captured screw?

As described.
Right size and got me back on the road. I like GM parts because I feel they are of good quality. Engine runs smoothly.

Just installed it, engine runs like new again
I had a generic cap & rotor set in my 2000 Chevy Astro (6 cyl. Vortec 4.3L), also purchased on Amazon. It only lasted 15 months for a total of 3,700 miles. We don't use this van every day. This month the engine started missing on one cylinder, with the associated rough ride and lack of power. The AC-Delco set cost twice as much, but it fixed the problem immediately. I'm confident it'll last longer than the previous set. My attempt to save money last year, as is so often the case, resulted in having to buy the high-quality parts after all. Not to mention the extra hassle of removing part of the dash and the doghouse for the new installation. I will keep buying AC-Delco parts for the Chevy from now on.
