best source of power for my Durango.

I just bought a 1999 Durango SLT and was looking for a little bit of extra power for this 5.9 Liter, does anyone know what will give me the best bang for my buck?

One thing I did on mine was to cut the sides of the airfilter box out. Then I installed a K&N air filter. It added a coulple of horses. Make sure the filter is seated properly so you don't get any dirt bypassing the filter, this is bad. K&N air filter.... about $ 40.00. Cutting sides of airbox...free. Getting your Durango to sound like moms stationwagon with the air cleaner cover turned upsidedown...Priceless. I got a nice little rumble after cutting the airbox and using the K7N air filter. Have fun.
