hi
being new am fitting a k&n gen 2 to my FRS at the weekend

was wondering if anyone has any pics of what it looks like in situ ??
looks like it comes with a bag like cover - is that right??
have seen a few FRS engine bay pics but none seem to have the filter fitted, or is it that you cant see it when it is fitted??

confused

thanks in advance for your help !!!

The Filter is behind the NSF Wheel..

nev_cup

its under the battery tray so you wont see it,

ye its got a water proof bag with it,

well worth it, love the filter and you can hear the noise of the turbo spoiling up.

dougfocusrs

ok
the missus has just got me one for my birthday !!! fitting it at the weekend
fitted K&N to my prev cars - should this one prove any easier/more difficult??
any fitting tips?

thanks

Does the bag come with it or is it extra?

Still aint go round to getting one.

Always seam to spend my money on something els

nev_cup

bag comes with it and its really fiderly, instructions are good but fitment is crap, rob @ssc has had to make a bracket up,

ive been messing about with mine for weeks and finaly got it perfect,

dont forget disconect your battery, then go for a 30min drive cycle so the ecu can get use to the extra air,

or you will get boost problems like i have,

still havent had time to do the drive cycle

dougfocusrs

disconnect the battery - is that to reset the ECU so it goes into learning mode??

when you say its a crap fit, what are the problem areas?

am doing bluefin and a DV36 dump valve and stainless steel boost pipes all at the same time - is it wise of me to do that?

nev_cup

dont do dump valve unless its a re-circ to replace the standard one, you will gain nothing apary from stalling and over fueling, if you like the noise you will hear it through the filter, trust me thats loud enough,

the bad fitting is just make sure its sealed and there is no air leaks,

the filter pipe is smaller then the standard hose if you get me.

ye disconect so the ecu learns it, do it everytime you add a mod or if you have bluefin, re install it.

nev_cup

please dont do dump valve,

try the filter first, you will love the sound of the turbo spoiling up and wont want the DV.

spark

What does it sound like with a atmospheric one on?

nev_cup

i wouldnt know mate. and dont want to find out,

dougfocusrs

i thought if i fitted it properly- with stainless steel boos pipework upgrade and samco's and used a top quality dv36 it would all work out ok, then put bluefin on and drove the car in learning mode, all should be ok

dougfocusrs

ok
got the filter today - looking at it and feeling a bit
do you really have to jack the car up in the air to fit it properly?
it looks quite tight/fiddely

ANY MORE TIPS/ GUIDENCE would be appriciated

dougfocusrs

hi

fitted filter - parked car on edge of the kerb so i was able to get underneath no probs !!!

took battery tray out to ease access !! K&N instructions are not exactly the best in the world !
got it on and took my time to make sure no leaks etc - took car out and the sound is awsome !
you can hear the turbo and the non atmos DV as well !!!
as the battery has been off car is in safe mode - anyone know how long this lasts??
its stalled twice when i fitted it before i took it out - but this is to be expected i suppose

nev_cup

takes a 30 min drive to make it learn,

Willow

What type of drive tho????

Ragging it or gentle???

Using all the rev range in all gears????

Need to know as just fitted mine and it drives like a bag of shite!

dougfocusrs

did you take off the battery for 30 mins?

mine ran crap - stalled a few times in the first few mins, but has been fine since, i have a bailey dv36 as well and (touch wood) its never stalled once

dougfocusrs

Willow

so let me get this right - i am thick!!!

Disconnect the bat for 30 mins then take it for a 30 min drive???

Need to know as have a car show in my local area at the weekend and need it to be right.

dougfocusrs

yes !!

just disconnect the battery for bout 30 mins, then re connect, this will put your car into learning mode - drive the car for about 30 mins, in this time the car will learn its getting more air, and adjust the mixture accordingly
this should solve your probs.
this was advise given to me on here and on the RSOC website and it worked
let us know...

Willow

Will do!!!

Willow

nope still no good - did as you advised and it's still not right.

It'll pull like a train through 1st and 2nd all the way to the redline - then in third it gets to 5000rpm and starts to cough and tries to suck more air but can't

In 4th it's the same but for much lower in the rev range????

I'm running it with a decat pipe and no dump valve at the moment - I've also got the stainless turbo boost hoses. Can't see why this would stop it working tho.

Can anyone help???? I'll try just about anything.

dougfocusrs

ok if your car was running fine before it has to be something to do with the filter

check the u clap connection is on straight and the air flow meter and sensor is on correct and that the plug is correct

take out the battery tray to allow direct access to this - make sure all your pipes are ok- no kinks etc, as you have a dump valve, check the blanking plug is still ok

Willow

Cheers Doug!!!

Drove to work this morning and it's all fine??!!!

Just wonder whether it's the icey cold air??? Could it have been causing lack of detination in the fuel?

It's a bit warmer this morning and it pulled all the way to the redline in all 4 of the gears i used - Ran out of road!!

Performance was amazing!!!!!

Will check all componets as you listed tho just to make sure - if i take the battery out again am i going to need to do another install run??

dougfocusrs

you will if you take off the battery, i just found it easier to take out the battery for access - you can access from underneath, i drove mine to the edge of a kerb, with the front end hanging over so i could get underneath and access was ok - beats using jacks and axle stands !
its fiddely getting in there, its not the best fitting bit of kit, the bits i listed are the ones to watch - i took about an hour tripple checking the bits as these are the ones that will cause the car to run bad

Focus_RS1658

Also it can run and you will have no power gains if there are any air leaks..

Robert_Cox

what is everyones problem with a dump valve? ive always dreamt of owning a turbo car. . . with a dump valve. sorry, but i just dont think its the same if u aint got one.

dougfocusrs

i tend to agree,
if there are no probs - the fit one as they sound great, i really took my time and mine is spot on, no leaks, no stalling - its great

NathR

My K&N fitted as per what was provided with NO probs at all, has been on for 18months. After fitting my de-cat, Gen II + BF the car ran fine then the following week I fitted the rest of the Mongoose, car was crazy fast for about a day then ran like a complete bag of shite, wouldn't idle etc, but after a couple of days driving it was fine, so I know it's anoying but bear with it!

Loads of people have had probs with atmos DV's, I would and have just replace the standard Bosh re-circ with a DV-30.

Willow

Found the source of the problem!!!!!!

Not the Gen II at all!!!!!!! I had a leak on the Intercooler to charge cooler pipe so had no coolant - so it was trying to force hot air into the intake manifold!!!!!

Anyway - topped up with coolant and sorted the leak. Now it's

And WOW - it's a full 18MPH quicker at redline in all of the 4 gears i've used!!!!!

So for a Decat and K&N thats a massive improvement - Bluefin next!!!!

dougfocusrs

strange how it came about when you fitted the filter ??
glad its sorted

Willow

Got a feeling that it may have been low or empty for a while and the increase in air volume that was Hot instead of cold must just have caused the problem!!

Tis strange i agree!!

plynchy

Getting one of these things tomorrow. Already got a full Mongoose/de-cat, cant believe how much difference that alone made!

Roll on the weekend, more noise, more speed!

Kev.H

K&N rocks just a shame its the worst made peice of shit ever

plynchy

That'll be a vauxhall Kev.
