Ok. I'd like to buy a high quality MAP adjuster for my 2.5 YJ. Various retailers want $130. And we all know such an adjuser takes about 8 bucks worth of parts to make and can be manufactured by a competent DIYer. I am sure I am not alone in my demand for one, at least one that costs maybe $40.
Since everybody on this site probably runs upgraded intake,exhaust kits on their 2.5s that means you probably have about 1000+ folks on this site alone, who, after being properly educated, could go for one for one of these MAP Adjuster kits.
So, whoever has the skills at 4Banger JP, I suggest that you buy the parts, *manufacture a few thousand MAP Adjusters (start with a few) while watching ESPN, test/guarantee for quality, make this built in 4 Banger market consistently aware of them, sell through link to Ebay/PayPal. You'll net potentially maybe $30,000 (not including the cost of your labor & handling) from this site alone Repeat with other Jeep sites.
*(Preferably get to Bejing, set up shop in China and utilize cheaper labor and we can crank out a few thousand in a couple of days for the cost of the flight over)
