i had a K&N panel filter to replace my old paper air filter about 3 weeks ago, its supposed to let the engine breath better, increasing BHP and low range torque... are they really worth the money ??

personally I think the most extra bhp you're going to get by just changing an air filter is +4bhp (if you are lucky) and if you can tell the difference from standard with a figure that small youíre a better man than I.
I think the only thing these filters do is make the induction noise slightly louder and if you have music playing most of the time you ainít going to hear the difference - save your cash stick with the filter Ford deigned for the car. :)

If your running the car standard then no it makes no difference apart from noise. If it's induction noise you want drill a few half inch holes in the bottom of the air box. If you run it with a Decat exhaust system re map etc it will help as it has a stiffer build construction which stops it from collapsing So much under full throttle when sucking in the most air. In doing that people usually replace the intake pipe for a silcone or alluminium pipe for the same reason. Hope that helps

they save cash as they are washable and tested to work with the engine you wiont see a difference and thats not really the point it does help for better breathing a bit but the fact irt doesnt need replaced is the main reason

Yeah this is true, but most garages include a filter in their standard service anyway, maybe they would give a discount but I doubt it

true very true personally ive used them depending on the car they can increase mpg but like you say most garages have them as part of the service anyway suppose it comes downb to the person really if you want that extra few bhp or not

cant argue with that. ive had my panel filter for about 15 months now and so far ive washed it 3 times. my mpg has increased ever so slightly with it but there is definetly no difference in power or that i can notice. i like to keep the filter clean, which is probably what gives me the higher mpg but it well worth it for 20mins work and overnight to dry out!

i bought mine second hand from ebay for pennies but it was like new, not a spot of dirt on it!

Ive got a 57I kit of an escort (dont ask) on my focus and personally i think it just makes the car feel more responsive and feels like its smoother when your climbing through the revs in 2nd with your foot buried in the firewall where as going back to the stardard air box after a while i found the car sluggish lower down and i really missed the noise :P . Its a matter when its entirley personal taste i love my little knn roar think it suits my car and lets it breathe better (cold air feed fitted) if you want one go for it even if just for the noise I'm going to be getting one on my next car depending.

you got it set up with a heat shield covering the filter when i had a k n n 57i on an old car i had the filter with a shaped heatshield fitting round that protected it from the engine heat then i had 2 cold air feeds one was attatched to the inside of the front grill so you couldnbt see it was there and the second i had a section cut out of the bumper with a demon tweeks adapter bonded and colour coded into it all you could see was a rectangular split in the bumper with air feed attatched to the rear i admit the noise was nice and it was a bit more responsive than standard but the focus airbox can be converted easily first drop in a performance poanel filter then remove the noise supressor bit the small rectangular section on the airbox and you actually biuy a cold air feed designed to fit in here that runs down past the side of the battery to the front grill the airbox is now standard sealed and getting cold air then the main intake replace that with an rs intake

K and N 57i Kits and Cones of the like if i'm honest are all noise and no show on any car unless your running over something like 180-200bhp and work better on turbo engines. Its the noise that phsychologically makes you think its faster and smoother. People and companies claim that they get more air in etc which they probably do but with the way new cars are built with electronic fuel and air management the car will only put out the power the ecu is designed to give. Cone kits also make your car drink fuel.

Personally i'd only ever really use a panel filter on a stock car and do the cold air mod that ascot mentioned

If you want more power buy something like a bluefin or get a pro re-map done or something along with a panel filter

A bluefin for a 1.6 focus would give me at best 6bhp and 14 l/b of torque for around £300 id rather cut of my man parts than part with that amount of cash for tiny gains. Chips and remaps are best for turbo's, tdi's and highley modded cars that way u spend about 400 but acctually get a big difference from it (car/mod depending). My cone kit has hardly effected my fuel economy (currently around 32mpg at a estimate) its gone down by about 2mpg if that. Its set up so there is a head sheild, good supply of cold air so its not like half of these chav racer boy !Removed! waggons that they just plonk anywhere and leave sucking in nothing but warm air.

All that i have put on my car though most importantly can be completly removed with no trace what so ever where as modding the air box is ovious as hell lol. The only items i have put on this car that cant be removed are my leather seats (sold the old ones) and im soon to be fitting some parking sensors the rest can all be removed lights, stero etc.

If you set up a 57i kit properly and use common sence your laffing if you were serious about power youd get a carbonfibre enclosed kit by pipercross, take out a foglight fit the feed in the gap and use that or cut a hole in the lower grill on the bumper etc.

Or a Carbon Dynamics enclosed air filter. I was mearly given opinions....and as for the bluefin...it worked well on my ST170 and gave me quite a bit more torque....hence why i also suggested a remap instead for a different car.

As for fuel consumption once again i am going by previous experience. I fitted an enclosed filter kit to my Leon Cupra R and it drank fuel like an alcoholic drinking sprits! I have always found perosnally that panel filters and the Carbon Dynamics BMC enclosed filter worked better though than previous attempts with cones.

Putting a cold air feed onto the standard air box is also hardly severly modifying it either.

So i'd appreciate it in future that if you disagree with something others have said that instead of shouting them down and saying they're wrong that maybe you approach it in a slightly more diplomatic way. Everyone has their own opinions.

Sorry if i came across that way im just so sick of people slating cone's to death and jump on pannel's as if there made of gold and murr when i genuinally struggle to see the difference in gains and losses with a proper set up cone package. I got my cone for £20 quid with a heat shield and a £12 bought me a new feed for it so for me to buy a pannel it would of been "un financally viable" (can't spell sorry) and true its not severly modding but you know how pickey some garages are when you want to trade in espesh when its your 1st car.

I will conceed that the amount of negative cone stories i have hurd myself is ofputting but so far im yet to be involved in one (touch wood).

On a different note what are st170's like to live with day to day on commute's etc i was genuinally concidering getting one in about a year's time but the insurance group 15 was a bit well offputting so i was leaning more towards the st fezzy (group 13) its worth saying either choice would be left standard.

I wasnt slating them I was just going by my previous experience. Unfortunately when you have a bad experience it tends to stick with you.


As far as commuting goes in the ST its suprisingly very good on fuel. On a motorway i get about 100miles to a quarter of a tank which i think is respectably quite good. However, on another note, around town i get between 70-80 to a quarter of a tank. Personally I prefer the focus st's but once again its persoanl preference. I know its 2 groups lower but dont think there is much difference in overall premiums.
