or you can get your own for $8 at grainger and spend like 20 cents on some brass tubing from a hobby store.
Us dodge guys have been doing that for 10 years.
In either case, those style MVBs are awesome. So what if the temp changes.. have your car set up to work with it. Do you have a nice set of the vital gauges in your car?
