I am changing to a different MAF setup this spring, so I have a LS1 3.5" sensor, 3" MAF pipe, and matching silicone/rubber hoses and clamps that I'm going to remove from the car sometime soon. Pipe has been used for about 1½ years, LS1 sensor was just purchased recently and has under 500 miles on it.
I can sell for $135 plus shipping, ($140 if paying with PayPal).
-3.5" LS1 MAF
-3.0" MAF Pipe
-MAF-to-Pipe Silicone Hose
-Pipe-to-Turbo Silicone Hose
-Clamps
Can take pictures if you want.
Let me know otherwise it'll be up for sale soon.
