That's all I can think of off the top of my head.Some of those aren't exactly "free" but they cost less than $5.Good luck.

There are lots of things folks have figured out to do with our cars. I love it, each and every one of these mods gives me a reason to spend time with my baby. A word of caution: watch out for the ported MAF, it is a good power making mod, but it can cause detonation in our cars and you must be prepared to deal with that if you do this mod. It would require that you do some other mods that cooled the engine and incoming air.
Once it's sorted out though, it makes good power.

Hey Ratio can you post some links with info on the other mods you suggested too? Thanks

Stock for now until I decide what to install.

 

I spend most of my time over on LS1.com, these things have been hashed over more than a few times there in the past few years. A search on that site would help you alot. Here are some threads and links that I like specificly:
Auto fan switch
Fog light mod/head light mod
Lose the autolamps, keep DRLs
Lose both auto lamps and DRLs
Cheap exhaust mod
Cheap exhaust mod pics
Throttle stop mod
$0.50 !CAGS mod
That should keep you busy for a while.

I second the comment about porting the MAF. If you're going to do it, either buy aftermarket ends, or find someone who bought aftermarket, and buy their OEM ends.

I paid a guy for his OEM ends and am so glad that I did. On the Z28, the port/polish MAF was great, but on the T/A, I got a lot of pinging, even with the other mods listed. So I had the OEM MAF ends sitting on the shelf and put them back on.

NO ONE MENTIONED THE installuniversity.com trunk release spring mod! Very important in the colder months.

 

I DO NOT recommend a set of ported MAF ends if you have an A4. One of the parameters that the PCM looks at to determine line pressure to the trans is the MAF sensor. If you port the ends or install an aftermarket set w/ the stock electronics the PCM reads it as LESS airflow because less air is being blown over the three MAF wires. If it sees less airflow, then it doesn't think that it's at WOT. Long story short, it will decrease the trans. line pressure at WOT. This will wear the clutches inside the trans VERY quickly, and you'll be looking at a trans rebuild sooner than you'd like. The gain from aftermarket ends isn't from the added airflow; it's from the leaning out of the air/fuel ratio. I'm running a stock/descreened MAF on my car, and it doesn't seem to be hurting my ET's. If you want to do it right, I'd recommend buying a MAF Translator and strapping the car down on a dyno w/ a wideband O2 sensor. Then you'll be able to adjust the a/f ratio @ WOT without risking trans problems. The other way around this problem is with custom tuning. I had Ed Wright set my trans line pressure to vary directly with my throttle position sensor. SO, I always get 100% line pressure @ WOT instead of wondering if I'm killing my clutch packs on the shifts.

Yup, if you are going to cut and port your MAF, get a MAF Translator.

I have a 2001 SS M6 and needed it to stop the car from pinging at part throttle.

 

OH .. and HPP3 and ported MAF usually don't mix.
