Thanks for the congrats! Currently, we strongly prefer the stock airbox. In the lotus, the Mass-air sensor is incorporated in the airbox. The diameter is different with many different CAIs, screwing up the MA calibration. The CAIs that make power are tricking the ECU to run lean. You can get away with this on the NA cars, but not a good idea w/ supercharger. The other issue is that the CAI doesn't help with the factory TB. We will be doing our own intake later with the larger throttle body, and with a calibrated tune.

We at least have a few actual measurements of the inner diameter of air intakes. There was a lot of misinformation in various threads about inner diameters (people throwing numbers around without actually measuring it). See the following thread:

Guess I better put a WTB ad in parts for a stock airbox. Car came with ITB CAI.



or..........wait for > "We will be doing our own intake later with the larger throttle body, and with a calibrated tune."

Thank you.
