Title: Cast Air Filters with Built-in Velocity Stacks? Post by: Stevemariott on February 05, 2019, 04:56:46 am Hello,
I recently picked up a pair of rectangular IDF air filters with 1/2” velocity stacks cast into the bases. Nice shape, it looks like someone painted them gold at one point. Question 1: Does anyone have any history on these, who carried them, or know when they started showing up? I’ve got an 8/85 Bugpack catalog that shows a version of them, and I’ve seen pics of them here and there with Redline logos cast into the tops, but I haven’t really seen them much besides that. Question 2: Would the short 1/2” stacks hurt power on a mild 2-liter compared to standard 1-5/8” stacks on a pair of 40DRLAs? It seems they were made for a Type 3 application, but . . . curious. With taller filters, of course. Thanks. Title: Re: Cast Air Filters with Built-in Velocity Stacks? Post by: runningmonkey on February 08, 2019, 14:17:05 pm There a cool bit of kit,
