3/8" NPT RIFE Standard IAT Air Temperature Sensor GM Delphi Connector -10 to 335°F (52-1243)

This sensor was quickly scaled with the stock ecu with hp tunes and reads really accurate and reacts super fast with the procharger setup great upgrade over the stock lazy iat sensor

The “OEM GM” doesn’t even fully go into then intercooler pipe. Reads 75° no matter what. Tons of issue. Installed the motion raceworks one, did the calibration. Perfect reading of IAT’s. 10/10 will install on every customers car from here on out.

I ordered this on 5/25/26, received 5/29/26✓. Realized I ordered the wrong size, and to get ahead of the wait ordered the proper size thinking I'll return the unused one. On 6/3/26, I started the return process and hit the submit tab and was told my items were outside the return window.. So, I looked and my items weren't on sale. So I should've had 30 days, if I read it correctly. So they should been returned less the restock fee, of which I would've asked if a credit could issued as I was planning to buy your LS valve covers with coil pack kit . So the one star is for poor return policy, and I'm out $82. I'm not a whiner, but you asked, so I told you. I got the corrected part and will let you know how you did after the Dyno and tune.
