the original air cleaner i have is in pretty bad shape. i used a ring of silicone to replace the rubber seal on the top. the cap atop the snorkel won't stay down for anything. is there any performance advantage to buying a new air cleaner? if so what kind?

also, i have seen a product at pep boys, forget the name of it, but it sits inside the air cleaner and has vents like a fan. its supposed to spin and increase your air intake and provide more horsepower and better gas mileage. has anyone used something like this? they run for about $6o.

the toilet bowl theory.............


Snake Oil, definitely not worth it (unless you can get one at the 99 cent store to try.............)

Your air cleaner sounds as if it's falling apart.

For best performance and driveability, replace it with another '70 or later slant-6 1bbl air cleaner. The '76-up ones that are ducted with a flexible hose to the front of the car to take in cold air are best, if you can figure out a place to put the cold air intake end of the hose. The performance advantage comes from having an air cleaner that's intact and working.

The open-element so-called "performance" type sold everywhere would be a step backwards; with those, you're not getting heated air when you can use it, to improve cold-engine driveability, but you do get barbecue-hot engine bay air when you don't want it, reducing the charge density and thereby reducing performance with a hot engine.

There is no performance benefit to a K&N air cleaner or filter element; just use a good quality "paper" (stock type) replacement element.
And eliminate waxy buildup on your kitchen floor, and make your coffee taste better, and get rid of tough stains, and win friends and influence people. Crappity crap crap, it's a scam.

hey now, don't forget about helping you lose weight and grow more hair!!!

Popular mechanics just did a dyno test on some of the snake oil performance dohickeys, the Tornado(what I think your talking about), did pretty much nothing, a cheaper version of the Tornado actually lost horsepower.

So SSDan you say that my open element air filter is a bad idea?, before you say something like "get a air cleaner with snorkel" those a extremenly difficult to get here, and when you get one is for something like 120 dollars or more. Is that so, what do you think about the idea to make a Air Grabber for my ´71 Duster? that will help to correct the barbecue-hot air effect?

So should i try to get one from the autoparts store or just go to the boneyard? Anybody know of a junkyard around Atlanta that has a good selection of MOPARS? And i just route that intake up close to the grille so she can pull in all that fresh air, right?

An auto parts store will not have a replacement air cleaner housing for you; you'll need to get one from a yard. Use www.car-part.com (searchable used auto parts) to find a wrecking yard that has the part. Search 1977 Dodge Aspen air box/air cleaner (so you get the cleaner assembly that's equipped to take the duct hose), then on the next page set the year range to 1976-1980. Results will show all engines (because this is an uncatalogued part)—make sure you get one from a 225-1bbl engine.

The duct needs to be routed so it gets cold air, but so that rain can't get in. Most of the factory setups are routed to a hole in the radiator support panel adjacent to the battery.

Pull-A-Part is one Atlanta junkyard that has a lot of '70s Chrysler products, and at pretty cheap prices too. It's where I bought my Super Six manifolds, not to mention the throttle body and elbow I'm going to be using for my fuel injection installation.
