Spark plug NGK or OEM Toyota

I like my NGKs a lot. Never had any issues with them and they perform well

Honestly I think NGK plugs are better. Either one does the same thing, but I've never heard of a bad NGK plug, even well beyond its normal useful life.

I stick with ngk iridium

NGK Ruthenium 95125.. I ran a set for 25k miles w/o issue on Stg 2 E85 tune.. their gap barely if at all budged.. probably could've kept using them.. ymmv.

i just switched over to some ngk 91006 last week which smoothed out the idle. haven’t put enough mileage on them to give a solid review but it’s what many recommend and the car felt great at the track this weekend so i’d say they are definitely a solid option.

After further review i returned the autolite plugs and got NGK LKAR7BIX-11S Iridium IX Spark Plug (93501 Iridium Ix). ????

I also paid roughly $50 for a set of 4 iridium NGK spark plugs for my Audi a few years ago....even with an extra cylinder or two it shouldn't cost even half as much as they are estimating here.

On Rock Auto Denso...Denso double platinum spark plugs for $4.32 each, but I would opt for the NGK Rutheniums for $8.32 each because they last longer and provide better combustion in these older engines

Have them for 15,000 miles on these and frankly can't tell the difference from (spec. plug) with original that it replaced. Gas mileage is no better and no worse.

Well, shit. I just put new plugs in two months ago following what EQT recommended then! I didn’t know of these failures with projected tipped plugs. Guess I should have spent a little more and bought non projected at the time, dammit.
