The Donaldson P577066 appears to be another suitable replacement for the FL500S, although they don't publish their 99% efficiency rating. It does say 50% at 6 micron, which I believe makes it a pretty good contender.
Yes, yes really.
Have a look at this article from Donaldson, or watch some of the LSJr videos at their factory.
To wit: "An air filter becomes more efficient as it loads with dust, providing your engine with enhanced protection — right up until it reaches its maximum restriction."
Thanks for the thorough write-up! I'm with you on the torque specs, realistically good'n'tight is perfectly fine but I sleep a little better running things with a torque driver.
FWIW, air filters get more efficient as they load up - for maximum engine protection/cabin freshness, it's actually...
BMW doesn't quite have paint to sample like Porsche, but they do offer an "Individual" paint upgrade where you get your pick of 160+ colors for $5k. Honestly struck me as a pretty good deal.
One thing I haven't seen mentioned yet is don't be afraid to build up a little cylinder pressure to help seat the rings. Get some boost and throttle going up a hill (obviously don't lug it, though) but keep the rpm reasonable.
Once mine gets here, I'm going to do an oil and filter change at...
I suppose so, but you could make the same argument for the 2.0/2.3 and evidently they saw enough value the in the latter to fully redo it for the MPC architecture.
I never could figure out why Ford offers bored or stroker versions of their engines as part of their standard lineups, always...
I'm active over on BITOG a fair amount, the Wix filters are mixed on QC. Best bet (at least for now) is still the PGI 10k mile filters - Microgard Select, Carquest Premium, NAPA Gold, STP XL.
PGI now has a 20k mile filter with a mesh media backing, but the efficiency is slightly worse than...
I believe the Motorcraft filters are made by Purolator/Mann-Hummel, so you should be fine for legitimacy.
That said, they suffer from poor efficiency and the soft black glue of death....
FRAM used to make the best filters on the market (the original Ultras) before First Brands' cost cutting started. Yet another victim of private equity groups...
Is there even another "upgrade" engine option besides the smaller of the two Gen 6 small blocks? They have that twin-turbo V6 floating around the parts bin but they seem content to leave that exclusive to Cadillac for now.
Would you guys say the tune is worth it for a manual? It seems like more of the comments are about the improved slushbox shift strategy than the power increase.
