Howdy from N AL, excuse my ignorance of this site, just discovered it so I'm still trying to figure it all out. I recently bought a '97 Mazda B2300 5spd SE Cab Plus and I'm really liking it especially the 26.9-27.3mpg. I had a '79 Ford Courier (made by Mazda) back in the mid 80's thru 93 when my son took it over so I thought I'd try another only to find out Ford made my Mazda. The way manufacturers do any more you can't tell the players without a scorecard. As I said I'm liking it so far and looking for more ways to increase fuel mileage, so far I've discovered a previous owner has installed a Tornado in the air intake between the MAP sensor and and throttle body in what looks like a silencer (increasingly tapered from 1.5" on inlet (where Tornado is) to approx. 2.75" on outlet with holes made into the tapered part) is this efficient? The outlet of the air filter is only 1.5" so there wouldn't be any air flow increase by removing that center section.
