MAF Z32 Plug (Nissan 300ZX)

thingiverse

This is a custom-made plug designed specifically for the mass air flow sensor (MAF) used in Nissan Z32 300ZX Twin-turbo cars. I created this plug myself because I'm running my RB26DET engine on a single turbo, and it's equipped with a MAF from a Z32 installed into a 4-inch pipe. Instead of buying an unbranded one for $15-$25 or waiting two weeks, I decided to design and print my own using just 4 meters of ABS filament and about an hour of designing time plus another hour for printing (at a speed of 15mm/sec for higher accuracy). This plug is engineered to work with the cheapest electrical terminal connectors available, which have a geometry size around 3.3x2.2mm width x height. The plug features a fixation point inside it where terminals can be secured, but I didn't include an outside fixation clip because it fits snugly onto the MAF sensor's body when attached. If you want extra security, you can modify the outer perimeter of the plug to add a custom metal or plastic clip by cutting a slot into it.
