Owner reviews for spark plug

New APR Spark Plugs, APR Ignition coils, PCV and Hoses

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.

I went with [Brisk ER12s](https://www.fcpeuro.com/products/vw-spark-plug-brisk-racing-er12s) plugs. They are one of the plugs recommended by EQT and I have been happy with them so far. Cheaper than the NGK/Denso plugs but downside is that they are silver based, so they will wear out faster. I am at 10k miles on them now and starting to feel a little rough idle; time to re-gap or replace them.

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.

FWIW, I just had spark plugs and coil packs done on my 2016 Jetta, $185 out the door at my local dealership

I have used NKG FOR THE PAST 6 years on the car , no issues at all. Recently replaced them with Bosch OEM spark plugs , it’s same shit , no difference.

I just changed out my sparks and found out the previous owners put these garbage plugs in it lol replaced with quality Iridium NGKs

I ended up checking the ignition timing again, put in a new coil, new knock sensors, put in another fresh set of plugs, set the DPR MA to +5, and I failed my emissions test with the same results.
