Check for vacuum leaks. You may have a broken or damaged hose.

Was looking for the gain, which in the OP, .055 was recommended. 15k miles means yearly swap out which is fine with me, and before i end up selling, would put a stock set back in.

sailor Gap can be discussed like an Oil thread, here's the original comment from the thread:

On to life and gapping.

If you gap the spark plug to the factory recomendation of .050" you should see 30,000 miles from them, however reducing the gap will reduce your hp gains, as you want the spark to jump as far as possible without extinguishing it's self to create a better flame front.

If you gap the spark plug to .055" you should see 15,000 miles. This is the best compromise in my opinion. The gap make the spark huge and will give you a much improved gain over stock.

You can also gap to .060" however I do not recommend this unless you keep a set of hand tools in your car. This will make a very nice gain, however life until the gap becomes to large is very short. When I ran .060" I swear it felt so much better and was getting around 38mpg highway. However, after 8,000 miles started to misfire. and when I checked the gap they had grown to .062" and i guess .062" is just to much for the coil on plug to handle.
Fits the typical theory of largest gap that works consistently for the best results. .060" is where some start to see inconsistent results, may not work that wide for all.

Or go stock gap for longest life.

Uh... no. That's larger than the factory gap.

.049 to .051 is the gap they need to be set to.

mac.mogul Did you read the thread? Because the answer is in the thread.

ACHRO If i put autolite ar103s in my mk2 (exhaust and air intake for performance upgrades) will i see any benefit?

mac.mogul For most people, copper plugs would be a yearly replacement item. Not too bad at $3 each.

Ryokuro And also keep in mind copper plugs do not last very long. Although high in conductivity, their durability is the lowest.

I run the Autolite 103 copper plugs by instruction of FSWerks for the turbo kit. I change them every other oil change (15k).
