ETS Evolution 8/9 4" Turbo Kit Intake Air Filter

This SP-3605 filter replaces the filter on the ETS Evo 8/9 4-inch turbo-kit intake. I'd use it when servicing that larger-turbo intake and the old filter is damaged or no longer serviceable. The fitment is specific to the 4-inch turbo-kit intake rather than the stock-MAF intake, which uses a different filter. Match the existing intake and filter connection before ordering.
