Review on Ignition Coils Compatible with Lexus Toyota V8 4.3L 4.7L 5.7L 4Runner C1173 UF-230 UF-493 5C1196 - High-Quality Replacement Parts for Lexus and Toyota Vehicles by Chris Edgerton

I had to wait a few days to get the OEM spool so in the meantime I bought this one. It arrived the next day as promised and worked flawlessly for several days while I was installing it. Not sure if it matters, but I found it was a lot heavier than the original coil packs in my truck (a mark of quality?). It's just a matter of durability, which is usually seen as the main difference between aftermarket and OEM, but for a third of the price, it's probably worth trying. It takes 5 minutes to swap out, so the labor is negligible, meaning you can just keep a few spares and swap them out when they break. I have to assume 3 of these will last as long as an OEM. I keep wondering if I should have messed around with the OEM package, but at least I have a spare now. So if you want to roll the dice to save money, grab them plus a spare dice or two and you might get lucky. If you want to know OEM durability then they are great for temporary/replacement parts.
