3.0i Engine Mods?
 

I'm looking for simple engine mods to get some more HP out of my 2006 3.0i, nothing too expensive and tough to install (since i plan to do this myself) thanks in advance guys.

I'm not aware of any that actually work :(

There are not that many engine mods that you can get for the 3.0i, however did you look at Dinan? Dinan is expensive, however once in a while they do promos where you can get some products for half off. I had the engine software upgrade and the auto tranny upgrade, and i just ordered the K & N air filter replacement, which supposedly adds 4 hp and 5 lbs of torque, because it lets in more air.

Have Dinan engine software A/T upgrade and HP Stage I upgrade. Awesome really make driving smoother and somewhat faster although no HP change I am told. To do so you need to go up to the S kit for the X5 or supercharge it...which you just as well could buy an X5 4.4 for the price I have heard.

On the Dinan site, they list the the K&N air filter and the engine software upgrade will create +4 hp and +5 ft lb of torque.

I did the Dinan Stage 1 Engine software and the Stage 1 Transmission software 1 year ago and love it. It's not a huge difference, but it's enough to tell there's something there.........I also did the K&N air filter about 7 months ago.
I highly recommend the DINAN upgrades.....plus it's still covered with the warranty.
It takes about 3 minutes each to download into your computer.........They just ran a 1/2 off deal last month too.
I found out too late - I was going to get the Dinan throttle body added!!! It would've been a good deal at 1/2 off.

How did it affect your mpg?

It's actually supposed to help the mpg, but in reality, I haven't noticed any difference. It seems a little better, but I never keep track of it. I only drive it when the weather is nice and have only put 7,500 miles on it in 13 1/2 months...........
