Spark plug Denso or OEM Mazda
Replaced my OEMs this summer to Denso K16GPR-U11 and has been getting really good mileage and smooth idling since then. Now planning to try NGKs next time.
Pros: good mileage, smooth idling
Vehicle:
Volkswagen
Part number: K16GPR-U11
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.
Pros: smooth idle, great response
I've been running these Denso's for almost a year now, seems to be a good plug for the price! :thumbup:
Pros: good plug for price
Vehicle:
Audi A3
I've personally ran these plugs in my car with 40+ psi of boost and lots of ethanol for the past 5 years. Great plugs!
Pros: great plugs, ran for 5 years
Vehicle:
Audi
Part number: 5346
Ik22 is one heat range colder than stock,and I have installed these in many 1.8T & FSI cars from stock/mild tune/heavy modded and worked great.
Pros: worked great, colder heat range
Part number: IK22
Denso iridium are great for turbo cars
NGK are also good, but in experience denso iridium works better when running more than 1 bar of presseure
Pros: great for turbo cars
Vehicle:
Audi A4
I dunno about coil packs but I put in Denso Iridium plugs a couple months ago and they have been working out just fine...
Pros: working out just fine
Thanks for the all input guys, I kept the Denso IK22's at the stock .032 and they seem to work grrrrrrrrrrrrrrrreat, all my miss firing issues are gone (probably due to faulty old coils) and the old IK22's I had in there were probably looooong in the tooth with around 50k on them. I do notice the smoother idle and the butt dyno feels it seems to be a bit more eager to go from low revs feels so good to not have to 1/2 step on the gas so it doesn't go into high boost and misfire, drove like that for several months:facepalm:
Pros: smoother idle, eager to go
Cons: old coils were faulty
Mileage: 50000 km
Part number: IK22
When it is warm out the IK24's work awsome. But on cold mornings they suck for the first 3-5 minutes of driving.
Pros: work awesome when warm
Cons: suck on cold mornings, choppy, sputtered
Part number: IK24
All the recommended denso plugs have the wrong gap. They list 1.1mm gap for the 2.0t The recommended gap should be .7 to .8 mm Plus the "20" heat range misfired a lot in the cold for me (about 20 deg F)
Cons: wrong gap, misfired in cold
Vehicle:
