Hi another question. I got a 3.8L 2000 Mustang and i never owned one before i only had a 4.3L S10. im just wondering can you just buy a filter and put it on the mustang or would u have to go and buy the whole tubing etc..

On the 3.8L Mustangs, people have stated that replacing the stock air filter with a K&N drop-in replacement and removing the silencer (the snorkle that reaches down in to the fenderwell) gives just as much gain as a full-fledged CAI at more than half the price (I got mine at AutoZone for about $55)
so this is what i dont get though because i never worked on a ford and on my old chevy i just took the old air box out and just stuck a filter on the end and pluggd in the 02 sensors ... is it fairly the same with a mustang.. sorry im a noob ):
It's been a while since I took out my air filter but AFAIK there are two or three clips that hold the air box together. It opens up in to two pieces (one attatched to the engine, one leading down to the fenderwell), and you can just pull the air filter out and put the new one in. The snorkel can just be pulled out of the fenderwell, and it's been sitting in my garage for months. No real need for it.
Go to autozone/advance/napa ect.....
Tell them you want an air filter for whatever year your car is. Tell them you want a direct replacement k&n. Swap the filter in the car now for the k&n. While your changing your filter you will see the soft rubber thing that comes off your intake and goes inside the fender area. Just pop that off and toss it in your garage. Search silencer removal. That's what it's called.
ok doesnt look to hard so you guys wouldnt bother getting 1 of those ebay intakes do you? should i just take the silencer off and stick a k&n filter on the end of it?... would this give me more HP then a ebay cai? thanks for all the help guys
Also your not sticking anything on the end of anything. Your replacing the stock filter with a filter exactly the same in the filter box only it's made by k&n. Your just removing the little rubber tube part that comes off the air box and going into the fender.
For a CAI you're like at 5 (max and being very generous, you won't get this with a cheapy CAI and probably won't get it with a BBK either...) HP for the $199 BBK CAI. = 0.025 HP/$
For a SC, Find one used with Low Mileage for like $2000 (I'm not that familiar with these but I've seen them on CL for this and less. Once people decide to dump them, they want to get rid of them ASAP). for 50% (people boast higher gains like 60-70%) gain on 190hp = ~95HP more. = 0.0475 HP/$
PS. Buying this New lands you in the $3750 range = 0.0253 HP/$ range
Not only is the HP/$ higher... but at least with the SC you'll actually "feel" a difference and get the power gain you want.
IMHO.... People go for CAIs because it's what they can afford. Unless it's a windstar, I will file it away with the performance gains of a mach chin spoiler or a grill delete.
