Works well, worth the money

Written By MAY03LT, Kent, DE on Sunday, March 25, 2007

This item does exactly what it says.

I used a 1 3/8" holesaw to drill through my firewall and the bushing fit perfectly. I had to drill from the inside out, there were too many components in the way from the engine side. I would recommend making sure that you can fit a drill in the spot that you want to drill through first before purchasing, without a drill it may be tough to install.
