part, stay away from oil filters |
I've used K&N's with Mass Air for 13 years with absolutely no problems whatsoever. I even removed the screens and filed down the fins. I've used both brand new K&Ns and ones that I cleaned & recharged myself. Never had a code or a MAF fail. 4th & 5th Gen Camaros also come with MAFs, many put on K&Ns, and never heard of them damaging the MAF.
MAF's fail every so often. It'd be very hard if not impossible to trace it to the filters. I guess you'd have to see air filter lube caked to the wire in the MAF. I've never heard of anyone finding that. Heat is usually what kills MAFs.
Removing the lower baffles will definitely make a difference. I've done it with both a 305 and a 350 TPI, and it is noticeable. The difference with the "ram air" mod, which I have done myself, is that, while the stock intake is cold air, you're getting even colder air from the very tip of your grill instead of right in front of the hot radiator. There have been studies that show ram air doesn't really work and is just a marketing gimmick. I don't remember the exact numbers, but the conclusion was that until you're going well over 200mph, you're not forcing or ramming any air past your air filter. To put it another way, ram air will not increase cfm until you're hitting a ridiculous speed over 200 mph. The benefit is getting colder outside air further away from the engine.
The good news is you can remove the baffles for free, and build the ram air tubes cheap with a quick trip to the hardware store.
