I buy the recommended FL-400S because it is the best built of the Motorcraft filters I have looked at; note the silicone drainback valve. The FL-1A provides no significant advantage in my opinion.
Respectfully, since this isn't a honda forum, I disagree. Higher oil capacity alone makes it worth it, but greater filter area at a given psi will always equal a higher flow rate - or an equivalent flow rate at a smaller filtration rate. Many people, and almost all serious racers, run a dual filter setup for precisely this reason.
Plus, since the filter will flow more, the engine will be able to run at a higher RPM before the bypass valve opens. It's not a significant difference, but every RPM counts...
Of course, this is my opinion. I respect your opinion and your right to have it. :wave:
Another filter thread? It's not filtering anything over ?x&^% rpm anyway.
I bought a case of FL400's cuz it fits the wifes 02 Windstar too.
It's more important how you cut the 2 liter soda bottle to cover your starter anyway.
I would desire more info on this. I've been trying to think of a method of protecting the starter; plastic bags aren't cutting it. I'm thinking perhaps one could manufacture a shield that bolts to one of the starter bolt (on the other side of the engine so it doesn't affect the starter angle) and covers everything up to the solenoid terminals (shorting stuff is bad, mmk)? Might be something for SHOSource or Mike Kopstain to think about! I lack both the knowledge and wherewithal to do this, unfortunately (that, and I'll be in Iraq soon lol).
I must say, I've had much better access than I thought I would to here during my training.
Edit: FWIW, I run an M1-301 (FL-1A equivalent) on my wife's 95 ATX, and my 94 ATX when I had it. The fit was a little tight, but it was doable as long as you didn't install it too tight. If the subframe is all the way forward for whatever reason, I can forsee it being an issue.
