I've only had my car for around 5 months and keep hearing people talk about free mods, What are they? how much did it help.

I personally don't think they are worth anything. Free ram air, Coolant bypass on the Throttle body.

Theres a few of them. They are called 'free mods' cuz they dont cost anything, they are done be removing/changing something already on your car. Check out the installuniversity link.

Some people like the free mods some dont, gm high tech performance picked up 10rwhp out of them so they have to have some effect

I think the free ram air mod helps slightly, and in some cases descreening the MAF and even the 'cutting the EGR protrusion' mod (pre 2001 LS1 F-bodies) might help in many cases, again only slightly though.
Certainly ANYTHING involving tire pressures and/or weight reduction (both free) will no doubt help move a car down the track (or street) quicker.

i could defenatily felt a power gain after doing the Free ram air mod and removing the plastic plates. I could also hear a louder intake air whoosh sound after doing that mod.
