UF247 Ignition Coil

3 days of using made my engine run a lot better and gave it more power gas saver,and great price and fit and installation was smooth,no issues at all yet , my spark plugs are great i bought them without it because i had already got some new denos installed, wire was great ,

Went to leave work the other day and all the sudden my 2003 Toyota Corolla started coughing and sputtering, the "O/D Off" light flickered every time the engine stuttered and sputtered. Shortly after the "Check Engine" light came on and stayed on. I was able to get it home and take it to a local auto parts store the next morning, they hooked it up to an OBD scanner and told me it was giving code "P0303" indicating that cylinder 3 had too many misfires within a predetermined time and the likely cause was the ignition coil. Since you have to remove the ignition coils anyways to get to the spark plugs, and I wasn't sure the last time the spark plugs were changed anyway, I wanted to do it all at one time - spark plugs and ignition coil. Problem I had was that the auto parts store wanted about $75-86 per ignition coil, or there was a cheaper set of 4 for around $250. So needless to say I was happy to see the price on these ignition coils and read decent reviews on them. I watched a few YouTube videos on how to do the job, and installed new spark plugs and these ignition coils in my Corolla this morning, took about an hour but I was meticulous about everything. So far so good, the car started and ran great on the test drive, no more coughing and sputtering, and the check engine light is gone! I'll try to remember to follow up in the future and comment on longevity of these, but at this point I have to recommend these! Build quality seems just as good as the OEM coils I removed to replace. Seems hard to go wrong here at this price point and it's an easy do-it-yourself job!

Used on a 2005 Toyota Corolla. Almost 300,000 miles on the OEM Denso units. These were a perfect replacement and along with new NGK plugs there is no more misfire on #1 cylinder.

Worked great in a 2004 Toyota Matrix. No codes thrown and fixed the hard idle.

Fixed my 08 Corolla. Will update on lifespan. My car was a no start or run for 10 mins, then no start until it was completely cool. We thought it may be the computer. Then it ended up being a shorted-out coil. They fit tight, are very simple to install, and feel well made.
