This warmer is as new as you can get. I installed it but only ran the nitrous in the summer and I had problems with HIGH pressure! Along came fall and I used it for one time at the strip on 4 passes. Must say it worked real nice! Went with a blower now so I am parting out my Nitrous system. Comes with warmer, relay, and pressure transducer. Anyway, asking $175 Shipped. Can take Paypal or credit card over the phone.
