Greetings! We are sending negatively ionized air, into vehicle air intakes. Results are very interesting, including improved gas mileage. Please see Benefits Observed!
Right now we have two test vehicles: my 1998 Chevy Tahoe, and a friend’s 1996 Dodge pickup. We’ll have my sweet Lori’s 2007 Ford Focus in on it as soon as we can replace her nonreplaceable stock air filter setup with a part from Rock Auto. We do think that the most effective uses of this may be tractor and diesel, and we don’t have either one yet ☺
So we’re clearly looking for folks to join us, and help develop rules of thumb for many different vehicles. We have parts available. Please contact me, Jonathan Brickman, at jeb@ponderworthy.com , Facebook at facebook.com/motormercy , and/or Discord at JEBofChristTheLord#5999, or 805 SW Jewell Ave, Topeka KS 66606-1610.
Please do note that (a) the government of California has banned any modifications in air intake for vehicles made after certain years, and (b) if you have a warranty on your vehicle, this may void some or all of it! So do be careful and knowledgeable when you have fun, save money, and enjoy a bit more power ☺
And last but not least, if you enjoy engines, do try 
, it’s a bunch of great folks who have been and are much help to many. There’s a thread on this topic right here.
