I was weighting on my gear install and in an old MM&FF (i think) they had close-up pic of a TB to filter densecharger on a table, and it looked like they went down to lowes or home depot, bought some plumbing stuff, painted it black, and there selling it for like $145. in my opinion. Now I have no shame in having plumbing on my car, as I made a CAI out of plumbing stuff from Home depot myself for MAF to filter into my fenderwell, but what gives with the price tag.
