As stated above i decided to have a go at some tweaking with my K&N cais.........as i want wanted more sound and if i could get it maybe more BHP, so i purchased an RS ecu cover to relocate the ecu, once that was taken care i was the left with quite alot of space so i removed the old K&N box and pipe, as i had already purchased some samco hoses and clips i had a go a coming up with a different design which didnt need the box and pipe so i cut the end off the pipe and used that to fix the cone filter to the samco and after alittle trimming i came up with this.........it is secured using the orginal K&N mounting bracket and a cable tie which you cant see in the pic.

Before......

After.....

with regards to the orginal ford intake pipe coming from behind the grill i bought another one from fords at the cost of approx £4 and with the use of a dremmel managed to fix the funnel so to speak on the opposite side to aid cooling onto the filter.

Driving + Sound

Well just as i hoped the sound difference is amazing there is so much turbo whistle and if you like it a very loud sneezing sound when coming of boost at high revs, the revs feel alot less restricted now and i have to say that there def seems to be an improvement in the way the car goes up the road as for figures .....i dont know but as people say if it feels better then its a good thing and thats all that matters to me.

i have been running this change for about a month now and have had no problems at all, and for the money i think its a great little mod to go with my Pro alloy IC, Turbo back (decat) Mongoose Exhaust and DS mod C.

Cost + Time

Rs ecu cover approx £60
Samco Hoses+Clips £70
k&N cais.....( well the filter and adaptor)

Thanks Glenn

Looks great! I personally wouldnt want to relocate the filter to the engine bay though!

I have not encountered any problems/lack of power issues yet and if im honest when i had look at the filter when i removed it , it was very very dirty behind the fog light.....ill wait and see. I think alot of the reason apart from the cooler area behind the fog light so to speak is that position of the ecu, the fact that the RS ecu cover houses the ecu where it does opens the doors for alot of other options......

I wondered how you'd got on with this Glenn, top job you've done with the filter. Looks really neat installation

I've noticed the same turbo whistle with mine too plus a nice discreet sneeze if you lift off with decent boost on the gauge but before the Magnex gets too loud

Looks great glenn !!!!! very tidy !!

Wonder how long it will be before someone fits the carbon airbox from GGR for an RS into the ST engine bay ?? ..

I'd thought about going down this route too.
I've checked and it looks like there should be plenty of cold air coming in around the headlight.
Had considered a 45 degree aluminium pipe and this filter..........

Good effort, much better than the K&N CAIS, safer running the SRI anyway imo.

I cant foresee any problems now but in the height of summer i think you may struggle with intake temps, even with my ggr and thats a fully enclosed system it gets damn hot in there.

Glenn - looks like a really tidy job mate, good on you for having a go. Now you got me wondering why I just shelled out on a DSCI kit to fit at the weekend!

I noticed the two air scoops over the slam panel.....is this the norm on the facelift ST? The early one only has the scoop on the drivers side, which goes to the airbox. Where does the second scoop go on the facelift version?

I'd be interested to know how you get on with intake temperatures during the warmer times of year, obviously we're a long way from those right now.....!

Cheers.

on the face lift you get just the one air scoop on the offside of the engine bay however this is the standard slam panel which i just used a dremmel on hope this helps.

hello mate yeah just followed your ideas and added some of my own im very happy with the outcome, a great mod to an existing mod, i would have loved to folk out for the dsci kit but did not have the money so came up with this alternative.

Not sure what you mean here mate....have you added the second scoop on the passenger side?

hi mate what size of samco 90deg bend did you use?

any chance of the sizes of the filter too

Just measure the diameter of where the elbow will fit over the MAF and ask Samco for an elbow with an Internal Diameter to suit.

Then speak to K&N for the sleeve which will go in the other end of the elbow and a filter to suit

Are there any breather hoses that need to be connected somewhere?

I will try this same setup + add few flexible hoses to give the filter cold air. (If it works in skylines and such, will work here also...

)

no breather hoses needed just the rs ecu cover ontop of the other bits, i would have gone down the DS ind route i just didnt have the money to change it for that one .......it works well for me sounds great as well so much whistle and chattering noise when coming of the throttle ......Glenn

Looks very good, would be intresting to see if there was any performance increases, I'm looking at fitting the ecu cover and putting a blank on the k&n airbox

There's a few problems with doing that, the K&N box sits right up against the metal lug on the front of the engine where one of the legs of the airbox or RS ECU box mounts - so the box would foul the RS ECU casing if fitted. Second problem is that the K&N airbox actually uses that mounting lug for securing the bracket from their airbox, but the RS ECU casing uses the lug too.

You may be able to work out an arrangement that allows both to mount on the same lug.

Also I think you'd struggle getting the ECU wiring to reach over to where it needs for the RS ECU casing when the K&N airbox is still in place.

I hacked up a K&N kit to do similar to Glenn so have had a good look at what could go where.
