Dragg-on Posted January 26, 2004 Report Posted January 26, 2004 Im gonna throw a K&N filter on my 5.0 mustang, but I know that on a banshee you must jet higher so air flow matches the fuel flow, so does that mean on a fuel injected stang, fuel flow must be altered as well??? Quote
josegarcia124 Posted January 26, 2004 Report Posted January 26, 2004 is it a cold air k&n intake, just the k&n filter that fits in the oem intake or another kind of k&n air filter? there are many kinds of k&n filter/intakes systems for cars. i have a volant air intake on mine, which is similar to the k&n. from what i know, you dont have to do any kind mods to the fuel flow system. the k&n filter is just for extra/cleaner air, thats all. gives u a small amount of xtra hp & gas mileage! late jose~ Quote
Dragg-on Posted January 26, 2004 Author Report Posted January 26, 2004 I might go with the stock airbox K&N, I doubt It will make a noticable difference vs the nice chrome cold air ones, I just would love better gas milage and the extra HP, but Im wondering if it make your car run a lean condition, which we all know is not good!

PassionRE Posted January 26, 2004 Report Posted January 26, 2004 If your car is equipped with an air-flow meter or mass air flow sensor it will probably compensate just fine for the additional flow. On Programmed PGM systems,with throttle position sensor and MAP sensor, the O2 sensor will most likely compensate for it...I dont see a problem....Jim Quote
dirtbike killer Posted January 26, 2004 Report Posted January 26, 2004 You have 19lb injectors, which is more than big enough for a k&n on a stock stang. The more you mod it, later you might want to go to 24lb. You can put pipes and all the little stuff on it without changing anything. maybe tires Quote
Aussie Quad Racer Posted January 26, 2004 Report Posted January 26, 2004 Does the efi system use an air flow meter or a manifold absolute pressure sensor? Air flow meters will sense a change in airflow and compensate for the change. MAP sensors do not as they are only looking at the manifold pressure to determin the fuel requirements. MAP sensored cars will require the ecu to me modified or replaced if too much work is done to increase air flow. If the engine is standard and you just putting a K+N in it then it will be fine with either AFM or MAP sensor. As passionRE stated the o2 sensor can alter the injector pulse width to a certain degree but it only does this best at a constant engine load. Quote
superchicken Posted January 26, 2004 Report Posted January 26, 2004 it will be fine with a k/n, depending on the year stang it could have either a mass air or a map sensor.your injectors are fine until u really start putting money into it.i had a 89,with a 306,kieth black 10 1/2 pistons,X cam,stock intake and fuel system and it ran like afucking champ,it was really a sleeper.stock intake hollowed out two chambers from the top,fake cats,and oh forgot about the 4.56's in the rear.god i loved that car,made alot of $$ with it Quote
dirtbike killer Posted January 26, 2004 Report Posted January 26, 2004 88 and newer is mass air. Quote
SHEEDAISY Posted January 26, 2004 Report Posted January 26, 2004 86-88 stangs had a speed dencity computer . with this computer you can not chang the cam duration with out having drivability problems or bad idioling .the computer dosnt like change and will not no what to do with a cam but as long as you dont mess with the cam its ok. k&n will be fine just get a cone filter and boolt it to your stock plastic intake tube 89-up cars have a MAF(mass air flow) system that reads how much air is coming into the motor witch tell the computer how much gas to mix in . with both of these you wont have a problem with k&n filter oh and you should be able to get 250-275 hp with stock injectors Quote
onebanshee Posted January 26, 2004 Report Posted January 26, 2004 You will be fine, if it is fuel injected, a filter on a car wont need adjusment, especially on a fuel injected stang, I had friend with 88 or 89 5.0 and he had a lot engine mods done, and never touched the fuel or air. So you will be just fi Quote
ator Posted January 27, 2004 Report Posted January 27, 2004 You should go with the fenderwell style intake, (ON TOP) this will insure that you are not just sucking in all hot air. P.S. it's a BBK w/K&N filter Quote
Dragg-on Posted January 27, 2004 Author Report Posted January 27, 2004 you guys know a lot about this! mine is a 88 GT 5.0. so i shoulnt have any problems? Quote
Indubitably Posted January 27, 2004 Report Posted January 27, 2004 Kinda off topic, but a ford mechanic once told me that K&N filters or any oil based filter will mess with your mass air flow sensor. Quote
ator Posted January 27, 2004 Report Posted January 27, 2004 you guys know a lot about this! mine is a 88 GT 5.0. so i shoulnt have any problems? no, you won't have any problems at all Quote
ator Posted January 27, 2004 Report Posted January 27, 2004 Kinda off topic, but a ford mechanic once told me that K&N filters or any oil based filter will mess with your mass air flow sensor. That is completly NOT true Quote
