    My Volvo 63L's air cleaners are the diesel soaked foam rubber type.
    Man-O-Man, do I really hate them!
    They are messy, and the large O ring that secures the foam to the canister keeps popping off.

    I am thinking about converting the air cleaners to the paper pleated cone type.
    Does anybody see an issue with attaching them directly to the turbo?
    Should install a 45-90 degree elbow to angle the filter up?
    Would the engines run louder?

    I would really like to change them out for the above reasons along with the added bonus of making it easier to change out the oil cooler pencil zinc. With the old ones out of the way, the zincs are right in front of you!

    The crankcase vent is currently attached to the canister, with a couple of bolts, for bracing.
    My SNL is a machinist, and he says that he could make a couple of nice braces with his CNC milling machine.

    Thanks for your input and advice in advance!

    Does Walker Airsep or Racor have an off the shelf solution for the 63L’s, have you checked them first?

    I agree with pacblue. I'd much rather switch to a washable filter. Don't think it would be any louder

    As on some other threads, seems the Volvo turbo scream is pretty loud already. Not from the air rush.
    I don't think an air filter change mod will effect anything.
    Don't toss anything thing till your happy.
    Please keep us up on your findings and send pics.

    Thanks for all the good advice! I'll take pics before I remove the old unit.
    I'll have to measure the available space to see if it will accept a 7.5" X 11.7" filter.
    That sounds like more than double the surface area of filtration than the existing one!

    Sorry, 1000 Islands.."SNL" means Son in Law.
    I ended up with a Bully Dog 9" X 5"washable filter with 57 sq" more surface area than the stock one.
    Because of tight quarter, I had to install a 90 deg ell (chrome, of course!)and point her up.
    As for bracing, I will order tomorrow from the local welding shop a design that I came up with.
    2"X1/4" flat bar with a cross piece welded to it. Told my SNL that I really didn't need an exotic brace after all!
    After installation, I will submit pics, rcrapps.
