This is a must have for your 270, digital weather gauge made for racing! I primarily used it for reading the air density and jetting!

It probably a little less than a year old and is in mint condition…

Can check it out @ http://www.summitracing.com/parts/NKM-08425/

I purchase it with a “hard case” which was about a 50 dollar add to the price… Would like to get $250 shipped w/ hard case & calibration sheets… Send me a PM if interested or want pictures…
