Standard Motor Products Standard Ignition UF403 Ignition Coil

Nice looking piece of hardware, installed without a hitch. No issues with the one I was replacing, I just wanted to do some preventive maintenance on a used car I'd just gotten. Drove smooth for 1 day.Started the car 2 days after installing. Very hard start, very rough idle, and an immediate check engine light.Plugged in a scanner, which came back with a P2302: Ignition Coil "A" Secondary Circuit.Thankfully the trash service hadn't come yet. Dug the OEM ignition coil out and reinstalled it. Code went away as did the violent idle. Knock on wood everything is okay after a long test drive.I'm very disappointed as this was the same product my local auto parts store had in stock (at double the price) and also is listed as a heavy duty part on a popular parts site. Between this comparative shopping and the good reviews, it seemed this was a great deal.I might have just been unlucky and gotten a dud, but after all the hassle I would not purchase this again or recommend it to anyone else.

Meh, was supposedly a high performance coil.

barely over a month installed, failed, bad output on #1 terminal, causing car to misfire and stall. over 30 days so have to make a "special request" to amazon to get my money back. had to go to autozone for the part as this was a daily driver car and couldnt afford the downtime. would not recommend.
