    First initial Mk3 Focus RS induction kit tests from Auto Specialists are in!

    K&N ‘V’ foam test found a peak gain of 8bhp over stock induction, which isn’t too bad for a bolt on.

    What do you think, will you be purchasing an induction kit at those gains?

    Prices not released yet. Think they are still in development/manufacturing stages.

    Sorry to resurrect an old thread but do we now have some more results to add to this thread?

    I’m wondering how much gain the K&N drop in panel filter alone makes as its such a cheap mod.

    @dan-2, an air filter change alone yields no result except an increase in start up noise, the only induction kit i have seen that make claims (that are believable) and back them up are Mishimoto, they claim 12Whp and 15Wtq on the stock tune.  Beautiful kit, love that they kept the air box. scroll down and read the Engineering notes at the bottom of the page.

    K&N’s Induction kit makes claims but are not believable in my opinion. https://www.knfilters.com/search/product.aspx?prod=69-3539TB

    @o1turbo30v I have just dropped in a K&N panel filter, and yes there is a significant sound change from the induction system, but there is a noticeable performance increase, inperticularly the ease it revs now compared to standard.

    I doubt the performance increase of 30-odd HP given by K&N would ever be achieved but I would there is a minimal increase in engine output after fitting the drop in filter.

    I would also say cold start noise is roughly the same, the only time the noise increase happens is at low revs running up the rev range.

    If I’m honest I doubt many would feel an increase in power after fitting just a filter. They might think they do but only because they believe that. Realistically I don’t think a filter on its own will do much in terms of performance gains, if at all. Mostly sound etc.



    Mods:

    FOCUS RS HEAD GASKET/AccessPort / Tune+ Tune / Burble+ (high intensity) / Boomba Racing short throw plate / DMB inlays / Mountune air filter / Mountune RMM / Mountune Recirc / Milltek Non Res Cat Back

    @adw I will put it to the test I think.

    I personally feel a difference as the noise isn’t really that different over the standard system (potentially because I have left my sound deadening in place), but I am tempted to do some dyno runs in the near future, mainly because I want a base level confirming before the mods get fitted and secondly because I was to see proof of each mod and the percentage of difference it makes.

    But just from daily driving I can feel a difference from only the drop in filter over the standard one.

    One that I will be doing, just to see how much difference there is (if any at all) is doing a standard dyno run with and without the intercooler blanking plate fitted.

    I was commenting on this thread trying to find other induction systems that have been tested on the dyno so I could see other comparisons before I move forwards.

    look forward to seeing the results, will be great to see real data on improvements. may be worth noting ambient temp when readings are taken. I personally believed (but no data to back it up) a better response when it was -5 degree Celsius the other evening.

    @yorkis I’m fairly sure the ambient temps and altitude of the test rig is all logged on the dyno sheet.

    If not I will add them in, as for gain and responsiveness, I have been swapping the standard and K&N filter in and out to see if there is a difference in the same circumstances (as it only takes 2 mins to swap over its an easy comparison) and there is a difference to be felt and seen.

    I drove the same roads at the same speeds on the same day and temps and the pulls with the K&N fitted were much more responsive and the engine revved so much more freely compared to when the standard item was fitted, so its noticeable in the scenarios I have put the car in but I will get it on paper soon enough to show back to back read outs.

    I would like to see data on this also as I’m sceptical that just a filter change to a foam filter will make a difference. But i know swapping the induction pipes out for aftermarket ones makes no difference either as they is no bottle necks or restrictions the aftermarket piping is the same diameter as stock
