Need some help finding parts.
 

Well right now I've have been trying to find a really low priced cool air intake and exhaust for my 2008 xD. If anyone has any suggestions Would really appreciate it.

Auto Zone has a choice of Spectre air filters (not specifically cold air intake, as it comes with no tubing) but they appear to do the trick pretty well. ~$20-25 for the cone.

The filter swap does a well job esp for 25 bucks or make urself one with spectre tubing .. can be done with I'm sure for no more than 100 bucks

yup, what they all said. thats what i did

Will the stock xD tube work or do I need to get both tube and filter?

Just attach the end of the filter onto the tube. It's a one-size-fits 3 increments kit 2 inches, 2.5 inches, and 3 inches, methinks? just take off the air box and replace with cone.
