you'll have to excuse the dodgy image quality, guess thats what you get when you pay bottom dollar for a digital camera
the first measurement value is the measurement of the GT Snorkel shown, the second value is the measurement taken from my standard snorkel taken out.
I reckon I may have picked up on a difference too. I was driving down the freeway the other day and someone in front of me was doing 80, and we all know what thats like, so I thought I'd show him my appreciation by passing him at the correct speed limit... in other words I planted my foot

. I don't think I've ever had this much power at speeds past 80ks, it took off like it was running from a fire.
Not bad for $33.80 (Part #EFTVE 9A624 A)
