Wanted to know if any of you know the best prices on the internet to shop for air filter, fuel filter and nicktane cat filter.

look at our vendors that support this web site. i believe a few of them might even have free shipping if you order 6 or more. i know I've seen one of them have the fuel filters for $30. Don't know much about the going rates these days.

We have fuel filters, oil filters, and tranny filters. Check some of the other sponsors for the others.

Oil=local murrays auto store=$3.49 for the AC delco!
Nictane fuel=local Cat dealer=buddys mom works there=$12
OEM fuel=still looking, but got last batch at GMpartsdirect before prices went up=$16
Allison=some dude on ebay=$10

For the Allison, check any heavy truck service center. You can find them on the allison web site. The White dealer here has them for $6.80 each
