Owner reviews for spark plug

Yesss got denso coils and spark plugs off their site and they have been great

My SO's Sentra is rated to 100k.... It's at 100k and 8 years of driving and they're still functioning completely fine.

im at 95k with the original plugs. no issues

I waited till like 100k to do my spark plugs on my 2013 Crosstrek, they were still good just not as efficient

Just traded in my 2015 Forester with 219,000 miles and the original spark plugs.

I just replaced my oem densos with some Bosch plugs that were labelled as being pregapped 1.1mm. I wanted them to be 1mm and checked with a gauge and Lo and behold they were already at 1mm. Whacked them in and improved my fuel consumption immediately.

NGK Laser Iridium 94124 is the OE plug. Just stick with the OE Plug.

I bought the plugs from Toyota (Denso). I asked for the old plugs off. The plugs I got back were NGKs that were installed at the factory. I can’t say I notice a difference really (except new plugs did seem to make a difference).

Definitely do NOT recommend Autolite spark plugs.

I tried it once after reading about that. Used ngk plugs. One of them seized and snapped on me trying to remove it. Only plug I’ve ever had seize.
