Denso- 6731201 DIRECT IGNITION COIL

Factory fit!

After diagnosing a misfire on one of the cylinders (thank you Advance Auto Parts for the assist there!) I found it to be a faulty ignition coil on my 2001 Toyota 4Runner SR5 Limited, 3.4L. Parts stores wanted upwards of $90 for this item, and mid-$80s for other manufacturers. Could NOT beat the price here. Amazon Prime shipping to the rescue so I didn't have to put up with the issue for long. 10 minute fix after removing part of the air intake and with 150,000 miles on it, my truck was firing on all cylinders again - LITERALLY. Packaging was pretty simple: one single coil pack in a plastic bag in the cardboard packaging box. No instructions came with it, but plenty of YouTube videos can help as well as message boards. Does not have the 10mm screw to hold it down to the engine block either, so be sure to keep the one on the old unit. No need to replace any wiring or connectors. Remove all the wiring attached to the faulty unit (make a note of where it goes) unscrew the 10mm bolt keeping it in place, pull the old one out, put the new one in, and reverse the process (e.g. screw it down, attach the wires). Now granted, it's been up and running for just less than 24 hours, so I may revise my review at a later date (hopefully not in another 150k miles though, just to make sure I let everyone know). Like the description says, this really was an EXACT replacement for my truck. In fact the old units were Denso also. May consider replacing the other 2 units on the V6 shortly.

Good quality replacement for the old ignition coils on my 2000 4Runner 3.4. Motor runs nice and smooth now with no cylinder misfires. I also replaced plugs and wires. Easy install.

Only able to use 1 out of 3.

Original coil packs were nesrly 25 years old. I was replacing plugs and wires so i decided to replace the coils as well. These are same Denso as OEM. Took ten minutes to replace all three. Truck fired right up, very pleased with purchase.
