Induction kit

but there will still be some to a degree, so if you must go down the induction kit route, an enclosed induction kit like the bmc cda will always be the best option. Unless you only care about getting a chavvy noise, where the k&n comes in to its own

I'd argue that the BMC sounds very similar to the K&N at least from what I've read on Focusowners and FFOC. :)

Also next to no heatsoak for the reasons Lopez said. It wouldn't worry me. I already have a gaping hole in my airbox at the momement from the removed resornator and have never noticed ANY heatsoak.
 
with them its just the induction kit filter (not panel filter) being used, which is ok if applied right - which it isn't with the likes of k&n cone filters. With the mentioned ones they are combined with heat shields and cold air feeds to make it a good kit, hence the mentioned ones being about £300 more

on the cars I've heard with k&n and bmc's, albeit predominantly vag, the bmc sound only really kicks in above 3k rpm where it gives a nice rip, whereas the k&n has just sounded like your average boy racers corsa all through the rev band

So the 57i kit should be similar??

Gobbling in air sound F.T.W

I had a 57i on my mk6 fezzy, sounded immense! And there was power gains aswell, seemed a lot better throttle response.

I have since replaced it with a K&N panel filter, basically the same without the nice sound.

If you do go for a 57i, make sure you get a good cold air feed.

Do you still have the 57 kit would it fit on a Focus?

Not sure, my kit that i got from esp was a kit with all the fixings needed for the mk6 fezzy.

The actual cone is the same, at a guess, but it's worth getting the kit for you car as it comes with all the fixings i.e mounting bracket, bolt, extension, cold air feed pipe, jubilee clips etc...

EDIT - Here's a post i made when i got my filter. 2 years ago :eek:

Notice all the fixings that i got with it. All comes with the 57i. Wish they made a typhoon for my car.

sounds great, and made the car perform better for me... ST150 system is restrictive on purpose to keep it below 150bhp (149) when the same engine in the mazda gets 165bhp. K&N induction kit with proper cold air feed have been know to boost the ST150 upto 165bhp..... for £69 you cant go wrong.

Mines getting rolling roaded soon and should be in performance ford september (fiestastoc and ZSOC meet).

it filters less, which would be a concern to someone who knows its purpose and gives no measurable gains, plus while filtering less it spews oil on to the MAF sensor. Bargain.

we get that you dont like K&N, you've posted it like 30 times already.... :p:o

Another thumbs up for Apexi. Made my own CAI relocating the filter into the wing. Thankfully the primera has a nice hole already in the wing so didn't need to cut much :). I doubt it really adds much bhp but once you start adding exhaust manifolds, cams etc it all adds up on the RR :)

are you part of the st150 lot that drive about southend/basildon at all? ive come across some of your cars before, just wondering

ps... 15bhp from a filter, behave. fiesta owners have a bad enough name as it is, youre making it worse.

you wont gain anywhere near that, id happily bet money that you lose power. a lot of design goes into airboxes, i wont go into that now, but a cone is a pretty daft idea unless you have forced induction where the heating of the inlet temps largly negates the warmer air breathed in anyway and also where forced induction quickly outflows the airbox.
 
thepharcyde, did you notice a big difference with the mods? I've just got a ST170 and am thinking of doing some basic mods to it. I've never looked into mods before though so don't really have any idea where to start haha

nope, i go up southend sometimes, but not with any crowd.

as said, the standard ST150 air induction system is TERRIBLE. *all* cone filters with *GOOD* cold airfeeds have gained 10bhp, as in fastford mag, performance ford mag, online, and users before and after power runs show....

do you want to bet some money that ive lost power then???? ;) seriously... I could do with some easy money.

ripped from FiestaSTOC (which was ripped from fast ford mag)

Hi Guys,

I see a lot of people starting new topics in this section regarding what induction kit to go for. In May's Fast Ford they did a test with different kits on the standard car.

They looked at the BHP and torque gains and also the Air Charge Temperature (ACT), apparently for every 1 degree c increase, your car can lose between 0.5 - 1 BHP!

For everyone who didnt buy it I have listed all the gains and results...

Test 1 - K&N 33-2280 Panel Filter
BHP Gain: 2.2 bhp
Torque Gain: 0.96 lbf.ft
Lowest ACTs: 29.4 degrees c
Score: 4/10

Test 2 - Pipercross 1622 Panel Filter
BHP Gain: 2.38 bhp
Torque Gain: 0.52 lbf.ft
Lowest ACTs: 30.2 degrees c
Score: 4/10

Test 3 - K&N 57i Induction Kit 57-0631
BHP Gain: 11.01 bhp
Torque Gain: 7.9 lbf.ft
Lowest ACTs: 18.2 degrees c
Score: 9/10

Test 4 - Pipercross PK-308 Induction Kit
BHP Gain: 10.4 bhp
Torque Gain: 6.02 lbf.ft
Lowest ACTs: 19.2 degrees c
Score: 8/10

Test 5 - Green Induction Kit SS-015
BHP Gain: 10.42 bhp
Torque Gain: 6.55 lbf.ft
Lowest ACTs: 24 degrees c
Score: 7/10

Test 6 - Simota CB-416 (This is an enclosed induction kit, like the viper)
BHP Gain: 8.73 bhp
Torque Gain: 6.95 lbf.ft
Lowest ACTs: 19.2 degrees c
Score: 6/10

Test 7 - Powertec Induction Kit PT12-35
BHP Gain: 10.68 bhp
Torque Gain: 7.17 lbf.ft
Lowest ACTs: 20.5 degrees c
Score: 9/10

From the results shown here, the K&N 57i is the one to go for... :thumbsup:

the standard airbox, not only has a very long (almost a meter long), and very twisty pipe (with 100degree bends) to and from it, but it also COOKS the air to a nice 30c for the engine to use... great job!

However, what is not shown in those tests is the effect the poorer filtration will have on the longevity of the engine.

Which to me is the most important factor.

i aint gona drive my ST for 500000miles so i think im fine ;) hell even if i did keep it all its life it will probably be dead by 100000 miles anyway.
 
~11bhp on a 150bhp engine just with an induction kit... induction kits don't even get gains like that on a 300bhp engine

either the original airbox and feed is a straw leading to a box of sand, or that test is balls

try it for yourself? a lot of mags "whine" about the fiesta ST being so down on HP, but its because ford aimed for a hole in the market for kids that cant afford high insurance groups of 170bhp cars like the clios at the time.

how do you keep hp down but still make it look good with a 2litre engine? well you restrict it. the airbox on my 1.2fiesta was less restrictive, straight in, filterd then straight out. the ST150 box doesnt do this. hell the pipe is SMALLER on the ST150 system than it was on my 1.2 :p

a 300bhp engine wont gain from a K&N as much because its designed straight away to be good, the ST150 wasnt, it was designed (detuned) to be 148bhp... not bad from a 160bhp lump ;)

oh, the ST165 has just come out.... guess what is changed on the ST165.... ;)
