The motor was built by a member of the Florida van council.I have had no trouble with it,just rinse and oil twice a year since I live a mile down a dirt rd.

The round filters do have a lot more surface area and will flow more. Here's a pic without the round air box but with the y-connector and 4" U-bend. Your twin hoses from the TB will be different on the 460. You'll need the connector, U-bend and air box. These are not easy to find at JYs.

Your ECM is a Speed Density system which means it's programmed for a certain air flow at a specific throttle opening, manifold vacuum, barometric pressure, etc. So a lot more air can't properly be used for HP. Because cool air is denser, one of the things it can use to richen the A/F and make more power is EAT/ECT or entering air/charge temp. Once it "sees" the cooler air it'll increase the pulse width to the fuel injectors to match the denser charge and even modify the ignition curve slightly based on it's programming. It'll make a little more power at the same throttle opening. It helps the big motor's MPG as well. You can use a little less throttle for the same result. So there is a return on your investment.

K&N has a new air box for the 97+ vans, if one could put a scoop on their hood, this snugs to the hood with a gasket when closed, you could really utilize it, I just won't pay $400 for it. What you need is to duct air into the box, be it from a hood scoop or piping from below the bumper, remember, dry air or rain will soak the filter media decreasing intake. | | | Re: AIR-FILTER HELP | Joined: Mar 2007 Posts: 4,463 Likes: 12 pooh-bah | pooh-bah Joined: Mar 2007 Posts: 4,463 Likes: 12 | I had a starter fluid accident and the box blew apart ! lol OPPS !
