I stripped and cleaned the heater valve, mine doesn't have an electric second pump. I have real trouble getting the car to bleed properly, even tried doing it facing up a steep hill with no success. Just like you I have more heat when the engine is revving higher, say above 2500 rpm. ------------------------------ Date: Wed, 2 Jan 2008 11:51:45 -0800 From: Peter Glaskowsky <[EMAIL PROTECTED]> To: [email protected] Subject: Re: Here's one for you folks that still cling to the K&N filter myth Message-ID: <[EMAIL PROTECTED]> > Date: Tue, 01 Jan 2008 13:29:25 -0500 > From: KMS- Brett Anderson <[EMAIL PROTECTED]> > To: UUC Digest <[email protected]> > Subject: Here's one for you folks that still cling to the K&N > filter myth > Message-ID: <[EMAIL PROTECTED]> > > http://home.stny.rr.com/jbplock/ISO5011/SPICER.htm > > You'll note that the K&N was the worst, or second worst, performing > filter in every test. > > Engine builders love K&N filters. > > Brett Anderson > KMS Uh, I read the data to show that the K&N filter was very bad at filtering, but very good at passing air when clean, which is a sensible combination. As the report says: "However, note how the AC Filter, which passed the smallest amount of dirt and had the highest dirt capacity and efficiency, also had the highest relative restriction to flow. The less efficient filters correspondingly had less restriction to flow. This illustrates the apparent trade-offs between optimizing a filter for dirt capturing ability and maximum airflow." In particular, the "Initial Restriction" test showed the K&N filter caused only a 4.54 inH2O pressure drop, well below all other filters. In such a test, lower numbers are better. However, the K&N filter showed very poor tolerance of dust loading, coming in third-worst on that test-- that is, it got "full" with around 240 grams of dust. Most filters had less restriction past that point, some of them tolerating much higher dust loading. So it seems like K&N filters would be the preferred choice if you're more interested in performance and not so worried about engine damage over short periods of time. That's probably only a reasonable decision for racing applications. . png (with no K&N filters in my car) ------------------------------ Date: Wed, 2 Jan 2008 15:02:56 -0500 From: "Matt Bader" <[EMAIL PROTECTED]> To: "'Peter Glaskowsky'" <[EMAIL PROTECTED]>, <[email protected]> Subject: Re: Here's one for you folks that still cling to the K&N filter myth Message-ID: <[EMAIL PROTECTED]> Yes, it is definitely a question of trade-offs.

Too bad they didn't test any graduated density/layered foam filters, such as the ITG. I've been using an ITG for quite some years now, and while it's hard for an owner to quantify effectiveness, I can at least say that the intake tract downstream of the filter passes the white glove test with flying colours. On the other hand, my M3 doesn't exactly get driven off-road through desert sandstorms.

When you click on the highlighted 'here' button the popup tells you they do original spec leder for all kinds of German cars ..incl BMW . Dunno anything about their prices etc so caveat emptor .... http://www.cut-lederservice.de/english/index_eng.htm Apparently the source for German auto leather for 160 yrs went out of bizniz (environmental ? ) in mid 90's so these guys are as close to the original cow as you can get . Having just had a pair of E30 leather fronts re-upholstered I can tell you that the leather on the seat-bottom (butt-holder ) IS thicker than on the backs . You may want to look for that capability in your supplier .... Bill Proud ------------------------------ End of [bmwuucdigest] digest(15 messages) **********
