Delphi GN10366 Pencil Ignition Coil

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.

Exact fit, as expected. OEM quality. 2/3 price of local store. Was able to clr CEL immediately. 10k miles on it, no issue.

Still Works well few months in, fixed check engine light, 2009 LexusRX350, easy install.

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.

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.

High quality and work like a charm. Don't go with a cheaper brand, buy these and you won't be sorry! Perfect fit for my 2014 Toyota Rav4.

I like the quality and the result but in all honesty - I had a struggle getting to the back three on my 2008 Lexus. I watched the YouTube video (several) regarding this and felt like it was doable. I can only say that you need to allow time to do this and release absolutely everything in the pathway to get the clearance if you are not removing the head. It can be done - but very tight IF you release all the other clamps to get slack. Great improvement now that the task is complete!!

Works perfect in my 2007 Lexus RX350. Easy install, all I needed was a #10 wrench to replace this coil. (My #6 OEM coil suddenly failed at ~65k miles, luckily #6 is on the front of the engine where it is easier to access.) I can't speak to it's longevity as I only recently installed it, but so far so good. I have put at least a hundred miles on it, in a mix of city and freeway driving. Using a bluetooth OBD II interface and Torque for Android I was able to monitor and graph my vehicle's performance, which matches it's OEM specifications as far as I can tell. The only minor difference I noticed is on the bottom sections of the OEM coil there are tiny little humps in the plastic, while the bottom section of this one is smooth. I can't fathom why that would make any difference. Saved a big handful of cash buying this part online and doing the job myself! One final note - if you are unlucky enough to have one of the rear coils fail in this type of engine configuration, in my opinion you might as well replace all your coils/spark plugs due to the difficulty of accessing them, especially if they are nearing the end of their life expectancy anyway.

Background: Check engine, VSC and Traction off lights came on. Used reader to figure out P0354 (Cyclinder #4 coil). I swapped the coils of cyclinder #4 and #6 to see if it was the actual ignition coil that had the problem. P0356 (Cyclinder #6 coil) error came on therefore it was a bad ignition coil and not wired or connection. Ignition coil came brand new in box and works great! Will update if any error codes come up or problems. Great product, would recommend buying this over CT (107$) because of price.

These are great and will last a couple years. Easy install, highly recommend

My Senna 2008 was misfiring so I borrowed an OBD2 diagnostic tool and determined which of the 6 coils was faulty and fortunately it was 1 of the 3 front easy to access coils. I ordered this new coil and the Toyota Sienna has been running perfectly since installation. The delivery time was excellent and it took less then 20 minutes for me to to replace, saving me hundreds of dollars in repair bills. I have only had the new coil for a short time, and only time will tell how long it will last but presently I gave it a high 5 star rating..

Easy to install, and works perfectly. Saved a lot of money DIY installed on "front facing" ignition coils (on engine).

I am sure this product works well. I wanted it to work well BUT I got sent the incorrect item. Unfortunately I needed on for my Lexus RX350 and I believe this is for the Honda/Acura something... item was packaged well and shipped quickly. I received GN10369 instead of the GN10366 -- difference was three prong connector instead of four. Easy mistake I suppose. As usual no issues with return. Worked out better in the end as I felt I should have bought the OEM Denso one for a few sheckles more so I had a second chance to do so.
