View Full Version : My impressions after installing new plugs

I've been trying to do a little maintenance on my car to squeeze a few more mpg out of her and to improve the performance some too. I ran some fuel injector cleaner in it and noticed a little better milage on half a tank. Then installed new ngk bk6es gapped to .028 and the opperation is much smoother. I'm giac chipped and I did not notice it pull harder at all though like some other people claim. It just seems smoother and no hesitation. I did spike 20 psi today. I'm not sure if it was the plugs or just the weather. Plugs were only 7 dollars and some change. I'd recommend the plugs to everybody since to just so cheap. I have a K&N filer coming tomarrow so we'll see if that bumps up my mpg a lil bit.

Also might be a good idea to change your fuel filter. I've heard its a b!tch. I need to do mine also.

Yeah it really is a bitch to do the fuel filter, I need to do change my spark plugs also.

Careful on fuel injector cleaner alot of those types of cleaners like to eat away at the grommets inside of the fuel system. Or even yet make the car run hotter and it will F up your o2 sensor.

Guy at school with a 1.8t GTI just ran that through his gas and guess what? F'ed his o2's and burnt his cat up from it. Car is missing like no other now.

Actually the fuel filter is much easier then most think. It took me 30 minutes to do mine while the car was on a lift and the right tools.

but see most of us dont have a full car lift and all the right tools.

lol

There are no wires...Coil-packs...No?

Different on 2.8s?

Well you dont need the lift. Just need to remove the bolts that hold the straps to the body. Then use a piece of wood to pull the tank down enough to get the 1 torx bolt that holds the filter in place. Best way to do this is to use a torx bit with a 8mm wrench.

Oh, so you have to move the fuel tank to get to the torx. Sucks....I need to do mine. Maybe I'll take a look tomorrow.

Yes you do. Just have to move it down on one end. There is a full write up on Audiworld.

i just did this too, no power boost, just smoother operation.

BK6REs gapped to .028"

1.8t has coils, 2.8 has plug wires

I think the rule of thumb to is decrease the gap .004 for every 50 hp. So yes, .028 for chipped cars. I think for ko4 audis, they run .028 on ngk bk7es. There is a good write up in the tech section.

The gap should decrease as you increase the boost, since you will need a smaller gap for the higher pressure inside the cylinder. I still run a gap of .030 to .032 while making 550 hp, but I will decrease that gap down to .028 once I move the boost up over 24psi.


Best thing is to only decrease the gap if your having a misfire issue at high rpms caused by the spark being blown out. Decreasing the gap too much can cause the ecu to lower the voltage and can cause less of the fuel in the cylinder to burn.
