🔥 Spectra Premium C-593 Ignition Coil: Reliable Performance and Durability for Optimal Engine Ignition Review

This product was dispatched quickly claiming it fits the 2004 Hummer H2 via Revain. However, when I tried to install, it wasn't even close.

Worked well for 25% of the cost. I have a code for an injector. Instead I switched to this one. My Tahoe was out kicking like an unbroken colt. This is a solution.

It only took 2 minutes to install. So far only 4 stars. We'll have to wait and see if this fixes the occasional misfires on cylinder #1. It also fits snugly on a 2002 1500 Silverado, 5.3 V8, 2 wheel drive!

ordered these because the price was good and I've had the occasional misfire at traffic lights as setting those misfires resulted in 4x the fuel economy 4mpg, fingers crossed they last long enough to get new ones.

Precise fit. Works great on my Silverado 5.3 2000. The DTC shows a misfire in the fourth cylinder. Install a new spark plug and then a new ignition wire. When that didn't fix the misfires I got this coil. Easy installation, easy to reach. For $22 I really should get a spare!

This reel definitely appears to be a quality aftermarket part, at least for once. It fitted easily into my 04 6.0 engine Chevy Express and fixed the misfires that the old bad coil was causing. It was very cheap here on Amazon which was also a fraction of the price at local auto parts stores.

My sons occasionally slipped the 03 Silverado. I tried new plugs and wires since it had 140,000 miles on it, it helped a bit but the code didn't stay clear. I put them on, they fit perfectly and now not only is the code gone but the rough idle that has been gone for as long as I can remember. Most notably, however, is that the smooth acceleration and shifting are back and noticeably improved, apparently at least some of the required coils were replaced long ago.
