Spark plug Autolite or OEM Subaru

The plugs are great-- zero issues, can't tell a difference.

I've put about 100 miles on them and the car seems just as happy as ever. Went for a spirited drive today out in the hills and the car felt responsive and strong through the power range.

My 2002 had a similar issue. In my case it was the spark plugs, $250 fix.

Autolite a103 gapped to .055" will give you about a 5hp increase and last around 30,000 miles

autolites 3923 platinumsgave me the same mpg as the expensive NGK platinum.....

As long as it’s not auto lite plugs you should be good. I’ve seen those things hinder 3 separate rigs from running right. Once one cracked 100 miles after installing them, half way through a trip we had to sop at autozone and replace plugs

Don't even think the Autolite or Bosch last as long as Denso/NGK spark plugs.

autolites were fine 100 years ago

now stick with NGK or whatever OEM was. its not worth it to be fudging around and what little your gonna save may be burned up in less MPG using some other plug.

I've had nothing but bad luck with Autolite brand.

I have a poor running Audi in the shop now. While it needs more than plugs, it has autolites.
