Accel® 140033 - SuperCoil Ignition Coil-on Plug

Installed these last year. I noticed a slight vibration after 9 months. We troubleshooted every thing from Injectors, Vac Leaks to finally the coils.1 or 2 coils, when hot failed. Replaced all COPS back to Ford Motor craft and the issue has not returned. Troubleshooting went on for 45 days unti this was discovered.

My coil came yesterday and installed no issues. I have 2 more to keep an eye on but I have my densos as back ups. So far vs the original supplier I bought a 4 pack from ordering them in singles as not given me any issues through TRUCKiD. Which is good. I still have a permanent code stuck in the computer from the defective mass air sensor this same supplier had sent out from jet. But the replacement I also ordered from TRUCKiD. Still 6 months later has had no issues. My hope Is the same with these replacement coils. Also I want to clarify my statement in my earlier review. That clarification is that you should not purchase these coils just as a stock replacement coil. These should only be purchased and used as a performance upgrade replacement. A good example would be if you are running a performance mass air sensor. Along with a cold air intake, performance spark plugs. An aftermarket performance exhaust, header ect as these coils create a higher spark rate vs stock. If you are just running a stock setup like the reviewer above like an 8 cylender 4runner and you have no mods like the one I mentioned above then you need to order the denso ignition coils or spectra or the stock or oem equivalent ignition coils. And for most Toyotas the stock ignition coils are the densos. And the densos can be ordered here from TRUCKiD for less then the accel coils. For those who have and are modifying their vehicles these coils are great for their intended porpose.

I am ordering another replacement I originally ordered a 4 pack for my 2013 from another supplier whose name I won't mention and 2 out of the 4 have gone bad. Bit the box was not in the best shape. Replaced one already with 1 from TRUCKiD and box looked proper and I have had no issues with that coil since now ordering a second one. To replace one that was defective. And hopefully these 2 will last longer than 6 months. I will say this TRUCKiD normally ships good products. So for mass air sensors and ignition coils I will trust TRUCKiD vs this competitor I used also for a jet mass air sensor. As my replacement mass air sensor also was defective but when I ordered it from TRUCKiD I have had no issues. With the replacements. As for these coils these are meant for guys like me that have been working slowly on upgrading their vehicles with things like a performance exhaust and a cold air intake. And a high flow cat on the s pipe so a performance header can be run and still be street legal. If you are not planning on upgrading to a performance vehicle. The stock densos or equivalent are what you should be using for ignition coils not these.

I bought these for the yellow casing and to replace my old coil packs that have high mileage 150,000 miles. I should have took the yellow as a sign. You know the sign in nature where something is brightly colored as a warning because it can kill you. Well these coil packs are killing my truck. If these come as an option for your 4runner just run the other way. Bought July 20, 2021. Installed on August 3, 2021. August 24, 2021 4runner check engine lights come on. The truck starts running like bad diarrhea. I check the DTC. Cylinder 4 misfire P0304. To check the coil pack I move the coil pack to cylinder 3 and reset the DTCs. I start the truck and Cylinder 3 is having a misfire. Diarrhea all over again. I file a warranty claim on the coil pack. I put in one of the old Denso coil packs that has 150000 miles on it since I had to send in the Accel coil pack. While waiting for the new parts on October 7, 2021 coil pack on cylinder 5 goes out. October 8, 2021 the new replacement Accel coil packs arrive the same time have a third coil pack go out on cylinder 2. I install all of the new replacement Accel coil packs on October 13, 2021. Oh wait one of the new replacement coil packs said screw it on October 19, 2021 cylinder 6 has its coil pack die. Thats two sets of 6 Accel coil packs with 4 of those Accel coil packs going out. I've been using the old Denso coil packs as back ups and you know what NO problems with the old Denso coil packs. Just buy the Denso coil packs for your 4runner.

Very easy to install and an added esthetic improvement. Would say to replace with this I'd you have extra cash instead of OEM.

I've bought Accel parts for years they perform better than stock.

These DO NOT fit a Forester XT Touring. Their website said it does. I ordered them, then wanted to return them they wanted to keep $60 since I was shipping back. Had to take a bunch of pictures and garbage to get the rest of my money back. Still haven't resolved it yet either.
