For spark plugs I always used NGK because that's what Motorcraft actually uses if I remember correctly. Autolites are complete garbage and always fouled out the few times I used them.

Pros: reliable, better than Autolite

Cons: Autolites are complete garbage

Vehicle: Ford Mustang

You can honestly just run stock plugs on the 1.8 with OTS tuning for stage 1/IS20/38. I ran these same VW/NGK "RS7" plugs including track use for thousands of trouble free miles.

Pros: trouble free miles

Vehicle: Volkswagen Golf

I forgot to mention that I installed brand new pre-gapped NGK spark plugs two years ago

I like NGK, but you can't go wrong using what the manual calls for.

Pros: can't go wrong

Now that I've done the job, I can't tell if it's just in my head but the car seems to have less power now. It was already a sluggish engine to begin with it but it feels like I need to floor it even more. Also, the gas mileage has dropped from 25 MPG to 22.5 MPG.

Pros: idles completely smooth

Cons: less power, mileage dropped

Vehicle: Subaru

Mileage: 60000 km
