K&N Cold Air Intake

So I am thinking of buying the cold air intake this should be around $275 to $300 for my 2000 F-150.
It is the 5.4 V8 and I also have a dumped magnaflow on it. Would it increase the sound of my magnaflow when I hit the gas if I put this intake on? I have a K&N filter and it has done great on my truck.I also go down alot of gravel roads and collect alot of dust.

So is this a waste of money or a good add on?

If you do an online search for “air filter test” there is a lot of very good information. IMHO, the CAI units are NOT WORTH THE $$ and won't change the tone of youe exhaust! Unless you are talking about a system that was specifically designed for a specific application there are very little hp/tq gains actually achieved in a street use vehicle and there are very few docs that these mfg’s can produce that actually show an increase in hp/tq in the power-band range of a relatively stock street vehicle.

I would avoid oil impregnated filters. While they have their purpose in off-road applications, Ford/GM/Dodge all have “watch-out” bulletins where the oil has contaminated intake sensors- they even have a training video for the tech's on this (flatratetech.com) .

If you look at the flow data, WIX HP filters flow 98+% of K&N and have a much smoother flow post filter plus excellent filtering, for a fraction of the price! The OE’s have an excellent air intake system the only issue that really exists is the plastic intake tube with it’s noise canceling design- that does reduce the intake efficiency a little but makes it very quiet!. You can use a WIX OEM HP replacement filter in the OEM plastic manifold box and either remove the plastic tube and replace it with a piece of pipe/hose, etc or remove the tube completely and replace the tube by building an air ram type intake into the air box manifold (where the pipe use to attach)- make sure ti terminates above the fan shroud to avoid water intake or fan induced pulsations.

DO NOT BUY THE K&N. Go to the summit racing website and find the summit racing brand C.A.I. It is made by K&N and is about $75.00 cheaper! I just bought it and took it out of the package and everything says K&N on it! go figure. It is part # SUM-F1140

I have a 1976 F-350 Super Camper Special with a 460. Does anyone know the list number for a Holley 750 with vacuum secondaries?
