I started this project Friday I'm now 85% complete in producing dual intake airboxs. This Saturday I'll be running the first test run on two different kinds of materials thickness. The new Air boxes will be lightweight ABS plastic 1/8" and 1/4" will be testing the two to see its durability. Plus I will be designing a snorkel for more air to flow into the box and will be designing a closure of the box so no HOT air from the engine bay gets into the box.. Here's a few pics of my project First template in black then transferred it to wood for more precise cutouts on the plastic sheet. made two walls locking into each other for more strength Front filter support so it doesn't put stress on filter for more stability. still working on that.
