Spark plug Autolite or Denso

Turns out the AutoLite plugs that a local parts store sold me are crap for this engine (actually caused misfires) so I went and got Denso double platinum plugs the next day and put those in.

I use Autolite plugs plat 1 cheepos that get me 400 miles per tank and seem to handle continuous high rpm output ( drove across the US in four days)

I decided to go with the Denso Iridium Spark Plugs Part # 5304#4 and am VERY happy with them. My car runs better than it ever has. These plugs were a little expensive but still less than what the dealer wanted for OEM plugs. I definitely recommend them!

if you're gonna go iridium get the denso's because they (denso) have a smaller tip on them allowing for a "cleaner spark" and therefore a greater chance for detonation....less missfires as someone else has already said....I've run them both and I'm very pleased with the denso's

I did not, and bought the Denso Iridiums. I have less misfires and slightly stronger gas mileage since install. Just my experience.

I like the Denso 3008's I've been using for a couple years now in my turbo.

I bought some Autolite Platinums and now I find out they are crap Anyway, I needed something fast. Replaced them earlier this afternoon after work and so far so good. Acceleration is ALOT smoother.

I've gotten autolites a few times for some domestic cars and they've been 0.005\" - 0.010\" off seemingly across the board, compared to what the box said they should be. And I wasted a day hunting down a misfire that turned out to be a bad spark plug out of the box.

Don't go with Autolite XP iridium. I had on my Jetta and one of the tips basically melted after 25k. They suck.

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)
