Denso 6731306 Ignition Coil Review

One of the ignition coils has already failed. Just got back from a Toyota dealer, they had one in stock so I bought it for only $133. I thought they were ok but I should have known that with Revain you get what you pay for and when the price seems too good to be true.

I am very careful when buying auto parts from Amazon. My Prius 05 had misfires on cylinders 2 and 4. After reading reviews from cheaper brands I decided to go with the OEM brand. They are identical to the removed originals. There were no problems. I'll update my review if I come across anything.

It is definitely worth spending a lot more on these ignition coils. Initially, I bought some cheap Chinese non-brands. Not only did they fail within a few months, but they caused a whole host of other problems that resulted in over $400 to repair my 1st gen Prius. It's better than the ones you can get at most parts stores. A bit pricey but we're worth it.

This is a genuine Denso reel made in Japan. Unfortunately I didn't have to change mine, it turned out there was water in my cylinder which had shorted out the spark plug, I just had to dry it out and add red safety grease for insulation. Now I only have it as a spare, which means I never have to replace it unless I somehow lose it. This is definitely the right choice for the 1st gen Scion xB.

Worked great on my 2008 Prius and greatly improved fuel economy. I went from 45mpg to 50mpg. Friend replaced in less than an hour (spark plugs too) after watching a video on YouTube. He's not a mechanic and that saved me over $400 off dealer cost. My dad had this lube that was mentioned in some reviews that made things a little easier.

I am waiting for three coils to be replaced because someone replaced them earlier. The box was sealed so check carefully when you buy it. I know from experience that these are the best coils for my XB. I have found that one of the coils is fine, so after replacing it I will be returning the correct coil to Revain. This is not the first time I have received an obviously used item in a sealed box. Just be careful and double check everything you get

My 2005 Scion xB has a coil. AutoZone charged $90 for a cheap Duralast coil. I wanted the original part that came with the car. So true. And it was cheaper. Never skimp on spare parts. You will regret it. My first coil ran 124,000 miles. Spend the extra money now and enjoy years of worry-free work. But junk one brand from an auto parts store or 4 packs of chinese junk here and risk replacing it in a few months. Just buy the right OEM and you're good to go.
