I really like this adapter and would highly recommend it to anyone who does not need an
oil cooler. Avoiding all the plumbing, connection points and opportunity for leaks is a great advantage, in my opinion.
It's worth noting there are a number of compatible filters if space is still an issue. Here's a short list of compatible Wix filters about the same diameter as the standard Ford filters, but shorter in length. All have the same mounting threads, anti-drain-back valve, and bypass valve (8-11 PSI).
Wix # / Ht. in / Filtering (microns - µ) / Burst Pressure

51521 / 3.79 / 21/ 325
51307 / 3.812 / 15 / 300
