Spark plug Denso or OEM Honda

Only things other than oil changes and brakes have been spark plugs at 100k and 200k, fuel injector at 120k, transmission fluid at 200k, and ac compressor clutch at 230k. 2012 automatic

There is no risk, EQT specifically recommends them. Been running denso 5749s for over 40k miles and change them every 10k. Send it.

Ive been running eBay denso plugs for 4 plug changes. You need to read reviews and look at the packaging to make sure they're not counterfeit. They've lasted me and performed exactly as they should.

I have a 2012 Civic LX (purchased new) and replaced the original spark plugs at 100k miles with **Denso 3483 (DXU22HCR-D11S)**—which were listed as compatible on RockAuto at the time. I’ve had great results and am now at 200k miles, looking to replace them with the same.

There is a noticeable improvement in performance when I cross over into the next country and refuel. This is what my denso iridium plugs look like after 20k km. I had a misfire. New plugs today, and the misfire is gone

Denso or NGk for anything and everything preferably dual ground spark plugs. I would get them rockauto as they have the best price and you can get the OEM brand.

Get the right dual electrode spark plugs, Denso or equivalent. They’re cheap, around $5 per plug.

So i just ordered a pack of 4s (the left one is from Denso Japan) from a local distributor carrying Denso spark plugs and of the 4, 3 are made in China and 1 is made in Japan. Comparing them side by side, the China ones definitely look subpar to the naked eye.

Ive got the densos twin tips in a vxr at present. One thing i can tell you is they dont like heat!!! i recently had a small coolant leak and they would misfire. pretty low heat resitance i think. work fine on cooler engines.

Had some Denso plugs in my '15 WRX (unaware to me) and the plug in cylinder 2 was fouled within 7k miles and caused a misfire. Turns out the shop that the previous owner took it to for the 60k-mile plug change decided to cheap out. I now have OEM plugs :D
