Which kit fits more engines?

The Perma-Cool. Its adapters cover 3/4"-16, 13/16"-16, 1"-12, M18 x 1.5, M20 x 1.5 and M22 x 1.5 threads, which Perma-Cool says is about 90% of automotive applications. The Trans-Dapt 1827 lists Ford F-150 use but no thread sizes.

Which one is easier to install?

The Perma-Cool ships with hose, fittings, clamps, screws and illustrated instructions, so you have everything for a custom mount. The Trans-Dapt kit's included parts are not spelled out, so check the box contents before you start.

Can I use either on a diesel?

The Perma-Cool is explicitly not compatible with diesel engines. Trans-Dapt gives no diesel rating for the 1827, so confirm with the seller before buying for a diesel.

Which filter do I need with the Perma-Cool?

A 3/4"-16 spin-on, such as Fram PH 8A, Perma-Cool 81008 or an equivalent. The Trans-Dapt 1827 does not list a filter spec.

Does either kit add oil capacity?

Perma-Cool states its kit increases oil capacity. Trans-Dapt does not state a capacity change for the 1827.

Is one worth extra money?

No prices were provided for either kit, so check the store prices on this page. Pay more for the Perma-Cool only if you need its wider thread fit and included hose and hardware.

Perma-Cool Oil Filter Relocation Kit vs Trans-Dapt Single Oil Filter Relocation Kit 1827
