First Impressions - K&N Panel Filter in LS 2.0

#Russ#Es# · 12-02-2010, 12:02 PM

There has been plenty of talk on here about fitting the K&N 57i Cone Filter setup on the LS/LT/LV Duratec. Thought I would share my inital impressions with the K&N Panel Filter - I haven't tried the 57i kit so can't really compare...

Ordered mine off eBay for AU$75 to my door from the US, which I thought was pretty reasonable. Really easy to fit - used a hose clamp to replace the tamperproof seal. Only mod required is to cut off a small lug that's on the connecting tube between the airbox and the throttle body. Noticed the K&N is a lot thinner than the stock filter, which obviously explains why it flows so well. Another thing you need to do is to start the car with the airbox unconnected and the throttle body exposed!

:

After driving a number of times with the new filter in place, there is definitely a little more poke down low. The intake noise (low airbox removed) is also slightly deeper. I have found it easier to drive in traffic...just seems easier to balance the revs, or maybe I'm just concentrating more??

I'd definitely recommend this mod for anyone looking to keep a stock look. I'd post pics, but nothing (new) to see here. Now I just need to reroute cold air into the airbox which may give another small gain.

Hey Russ,
Sorry I haven't answered your PM - not intentional.
Work, home, kids, sport have kept me ridiculously busy.
Glad to hear you sorted the filter out.
Fredo
PS - change your signature mate.

Another great mod and I am sure it will be even better when you re-route the cold air feed into the bottom of the upper airbox.

Loud?!

No probs Fredo, I should have had a decent look at the job before I PM'd...was pretty easy!

PS - cheers, all done.

Just a tad louder

I'm sure it would sound even better with a decent cat-back exhaust though!

do any of you guys know the part number for either the K&N panel or the 57i kit that fits onto an LS zetec?
There seems to be 1000000 different kits avaliable.

DZFord · 10-03-2010, 09:37 PM

Panel = 33-2877
Cone = 57-0595

And for the love of god - please make sure you go to Supercheap first to buy a new hose for the air sensor thingy (always forget the name) if you go the pod version!

Anybody know the part nos. for K & N and/or Pipercross panel filters for the LV 2.0 L petrol? Getting very frustrated trying to find out. The ones that fit Yank cars of the right year seem to be a different shape, and the UK sites I find seem to only have up to 2007 models - not sure if there's any difference.

DZFord · 07-04-2011, 11:42 PM

I think with the LV, Ford changed from a panel filter to a cone filter, but since I have an LS I can't confirm this for you.

Thanks. I suppose the easiest way is to open it and have a look...

Please do and let us know what you find!

In Focus · 22-04-2011, 09:28 PM

Well, I've just ordered a Pipercross filter for the LV. On special for easter at Team Torquesteer. Works out to about $73 including postage.

DZFord · 22-04-2011, 10:14 PM

What did you find when you looked in the airbox in the LV? Cone or panel filter?

In Focus · 24-04-2011, 01:26 PM

Arghh, I hadn't had a chance to look, because the car is in the panel beater getting some rear damage fixed. I got excited when I saw a discount on the Pipercross and ordered it straightaway, asking them to be sure they sent the right one for a 2010 Focus. Anyway, the Torquesteer guys said the Pipercross is a panel (even though it looked like a cone in the picture), and that I might need a cone filter, as Ford (in UK at least) changed from a panel to a cone at some unclear date in 2009/2010...

Torquesteer said they'd hold/cancel the order until I work out which is required, but of course I can't check. So if anyone has changed the filter on an LV 2L petrol recently, please let me know which is in there. If it makes a difference, mine is a December 2009 South African build.

Done a cheap *** job on mine.
Have the K&N cone air filter connected using the stock tubing and got it sitting in the exposed airbox resonator

DZFord · 25-04-2011, 06:36 PM

This may sound like a funny question but is your filter on backwards?

I always thought that with pod filters, the wider part connected to the intake tube, whereas the narrow part pointed away from it, if that makes sense. Correct me if I'm wrong, it may not make a difference at all...

I just had a thought and checked on the Ryco website. Their LV Focus replacement air filter is a cone style filter.

Funny you should say that, but I got hold of a neighbour with virtually the same car today and, sure enough, it is a cone filter (or more cylindrical really). I was pretty sure it would be, given the airbox itself has a sort of curve in its outer surface to accommodate it.

In Focus · 26-04-2011, 10:36 PM

Pipercross foam cone filter now being airmailed. Martin at Team Torquesteer was good enough to charge me the same for the slightly dearer item: I think he was tired of the e-mailing back and forth to work it all out.

I recommend their customer focus.

In Focus · 13-05-2011, 10:42 PM

Well, I just got the K & N cone filter. Thought I was getting a Pipercross, but I gather they don't make one suitable. Anyway, the K & N took about 5 mins to install, and I haven't had much of a chance to try it out, but... it sounds great. Not like a roaring tiger, of course, but more of a tomcat than a kitten now...

It definitely feels more responsive. I only had to twitch the ankle and the car seemed to leap forward. Tomorrow, I'll test it on my weekly run to my parents' place (35km each way, uphill one way). The normal petrol consumption figure is 7.6L/100km, so it'll be interesting to compare.

Incidentally, my (very, very inexpert) eye noticed the airbox intake appeared to be coming from the front of the bonnet, over the radiator, rather than beneath the airbox somewhere as in the LS/LT set-ups I've seen pictured on here. There was also a small square of a spongy material in the bottom of the box. Would that be for the crankcase? Probably a dumb-**** question, I suppose...

Anyway, very pleased with my investment so far, although it's only early days...

Harrye30 · 14-05-2011, 07:10 PM

I've had several encounters with K&N filters in the past on my father and brothers cars and after driving them both *falcon and alfa spider* Can say that they do make a difference low down. Just my 2c (:

In Focus · 14-05-2011, 07:54 PM

The numbers came out to 7.5km/L on the run mentioned above. The wind was a little gusty, and there were some clowns doing roadworks that slowed me down a couple of times. Early days, but it's at least comparable to what I normally get. Except the K&N sounds far better, of course...
