On my 3.2 turbo conversion I wanted to get outside cold air into cone filter rather than the hot engine by air. Designed and printed a air filter shroud which now puts the air intake source for the filter right underneath the wing opening. The two inlets are designed to allow water to pass through the shroud without contaminating the filter. No air restrictions as the openings have the same sq. inch area as the 3” tube going to the turbo. Printed in ABS andbBeen installed for 6 months without any issues. Intake temps pre intercooler cool down a lot faster than without shroud.
