Have you cleaned out your cowl lately?

I made a vacuum helper for my shop vac with 1" PVC pipe (1 piece about 12" long and 2 pieces about 2 to 4" long) and two 90 degree elbows. Don't glue the pieces together, so you can manually adjust the angles. Attach the PVC to your the shop vac hose with duct tape and then vacuum from the underside of the dash. This will allow you to get all the junk near the openings into the vent ducts. The setup will look almost like a candy cane, that you stick the short end up the vent and into the cowl space. Worked great in about one hour total. Best part was no more "face full of dirt" when I open the vents now!
