AFR guage

Ive had AEM on my last 2 sleds. Never had an issue. They say NGK ones are the most accurate, ive never ran one tho.

I am looking to buy a new a/f gauge for my turbo sled, has anyone tested the dobeck gen4? I have to say it looks kinda tempting to buy one.
 
NGK afx does not fog up. Best AFR out

also it does not water resistant, very slowest response and does not reliable for hard winter using.
went to garbage couple of it at last season.
but yes, most accurate.

I use and recommend the aem brand I've been running it for a few yrs and that's what we use on the sleds at our shop.
 
AEM is what i run.... got the motor sports version so i could mount my gauge beside my gauge cluster with the longer wiring. just get the gauge cup and seal it up with some silicone caulking.... works like a charm!
