Continuing down the intake, I wrapped the MAF sensor housing with the DEI Gold tape, and put a double layer of heavy duty aluminum foil around the accordion hose.
One theory has postulated that the location of the MAF sensor housing above the passenger side turbocharger means that “all of the hot air coming from the turbocharger will rise and heat up the MAF sensor housing”.
Perhaps, this step was an attempt to see if wrapping the MAF sensor housing and accordion hose would lead to a temperature reduction at the inlet pipe.
Here’s the morning drive results:
The dark blue line is the data with the MAF sensor housing wrapped in the DEI Gold tape. It (Gold tape and Aluminum foil) does not appear to have significantly altered the temperature profile.
In the afternoon the results were:
Again there was nothing notable in the results to indicate that the DEI Gold tape applied to the MAF Sensor housing led to a reduction in the inlet air temperatures. This drive took place on one of the hottest days yet, thus the temperature curve is higher than most others.
