Owner reviews for spark plug

NGK plugs have never failed me at my shop. I'm pretty sure they're NGK 3199 plugs

Can't beat the 2.5 for hassle free reliability. Economy sucks, though. I have had my 130k mile 2.5 Rabbit since new and I have never averaged more than 25-26mpg in mixed driving, but on the other hand I haven't done much more than oil changes and spark plugs on it.

i changed the plugs out for oem replacement NGK plugs (it had bosch platimun +2 in it) and a set of wires. and it ran just fine it was fixed. i then decided to swap my other coilpack back in and it ran fine no issues at all.

I put in NGK PFR7B plugs and R8 coil packs. Smoothed the idle out and judging by the butt dyno the rev/boost response seems great.

I run stock NGK with .026 gap as well and I've been anywhere from 10-18psi

Denso Iridium plugs work perfect in 2.0T Got them from Autozone for $8 each, smooth idle at start up and when warm, great response, made in USA.

The plugs were only part of the problem. (They were NGK VW/Audi part#1010000035AB, NGK BKB5EKU. Good plugs, lasted forever. Sure, they needed to be replaced, but the #6 plug well must have been flooded a time or two before the radiator was replaced last month. The metal plug jacket had a lot of green crud in it. I cleaned the plug jacket with cylinder brushes from Harbor Freight ($7.00 without coupon for an assortment 3 sizes in SS and brass) and finished with medium emery paper wrapped around a thin long screwdriver. The motor runs smoothly now, across the RPM range, without hesitation.. I'm wearing a pretty wide smile.

i might switch out the plugs again because my buddy got me some freebie bosch plat 4 and i wanna put the bosch single silvers in.

I installed brand new denso ik24 plugs gapped at .026 and I am still getting misfires.

The autolite is a cheap plug, not what is recommended to be used.
