Fixed light on Toyota Avalon.
Worked for my 2006 Avalon with the 2grfe V6, cleared my misfire code. For anyone who is uncertain if the coilpack is causing a misfire, do this trick If the coil pack is easily accessible: determine from the check engine code what cylinder is misfiring, AutoZone can check for free. Pull up a Google image cylinder number sheet to determine which is which, varies from vehicle make and model. disconnect battery then take that suspected bad coil and swap it for another coil pack from a different cylinder and note down that cylinder number. Reconnect battery and wait for the check engine light to come back on. Check the new code and see if it misfires on that different cylinder or the same cylinder as before. Different code= replace the bad coil. Same code= check spark plug, fuel injector, dynamic compression test.

Fits 08 Toyota Sienna 3.5
It’s a little different shape on top compared to original Toyota coils but it works great and looks great 👍. It took care of the misfire right away. Make sure to also replace the connector housing for your ignition coils because they get brittle with the heat from the engine and can cause a poor connection. Finally make sure to replace the spark plug along with the failed coil. Denso iridium TT should do the trick.

Bought for a 5.7 Toyota tundra
Love the quality and value of this product, product came packaged well with care unlike other brands. Painless installation and performs equal or better that factory for a fraction of the price! Bargain for an Ignition coil.

Parts fail not compatible
I replace my spark plugs the ones near the fire wall in my 2007 RX 350. I spend hours getting parts remove and finally got to the coils. Replace the coils with these Delphi coils. Replace everything because it requires to do so. Start the engine and my engine run sluggish and die. Turn the engine on again same thing. Turn it in again ran up the engine didn’t die this time but ran rough. I took the car around the block and there was no power when accelerating. Came back took everything out put the old one back in, engine run perfectly. Return those so call Delphi coils as fast as I can.
