Hi guys. For those of you with the K&N drop-in replacement filter, I was wondering if you noticed a significant increase in power or throttle response.<p>Thanks

<br>I installed during the summer and noticed a huge<br>diference in throttle response. The car moves off<br>the line without any hesitation. Before install there would be a hesitation when the clutch was<br>released. I am not sure if the car is any faster but<br>it is <br>certainly a nicer drive.<p>2.8 30v

Here is a previous posting on the subject:<p><br>Posted by Paul N on December 17, 1998 at 19:36:52:<p>I just installed a K&N airfilter (part 33-2125) in my 98.5 2.8. Installing wasn't difficult, you just have to move some plastic covers, intake, and a unplug a few wires to get the box open. The K&N filter is not as deep as the paper filter. It is also a tad smaller, about 1/16 of an inch. However, K&N assures me it is a correct fit; I went to technical support at K&N in Riverside and had them take a look. I recommend you install the filter to the top portion of the cover first, and it seals just fine.<p>Now for performance observations. (Of course its purely subjective with no scientific measurements! So please don't send me any flames!) Throttle response seems a little quicker. This would reasonable because, because less restriction allows quciker intake of air. The most significant thing I noticed is the change above 4000 RPMs. I have observed the 2.8 (30v) has a sluggish zone from about 4300-5000 RPMs. (The graph on Wett homepage confirms my observations.) With the new filter, performance in the slugish zone appears to be improved with better acceleration. Is this because it can get more air? Someone told me there is a butterfly valve that opens up at 5000 RPMs that allows more air in and that is why the jump in performance, after the<br>slugish zone If this is true, then the less restritive filter may be providing better airflow in the sluggish zone. <p>The other thing is the engine sounds better at the higher RPMs. I have nothing to ack this up, so it may be my wishfull thinking.<p>If you want a filter, call J&M Speed Center in Riverside, CA. The number is 909-688-7110 and ask to speak to Lisa. They are local to K&N (Riverside) and can get the filter the same day. Since this is a new part number (33-2125), other places may take longer. Now for the great part, the price from them is $38.95! Other places I called wanted $48. <p>Enjoy,<p>Paul

Well, I wouldn't say that it would give you a "significant increase" in power or throttle response - i think the only upgrade that would do so would be the supercharger, or another similar form of forced induction - but it does make the throttle response a little nicer, and it *might* be a tad quicker. Big emphasis on the "might." However, it only costs $40, and as long as it subjectively feels better, then why not spring for one (i have one myself, i can tell you it's better then a cone filter setup for day-to-day driving). <p>Happy New Year!<p>Edmund Louie<br>98 A4Q 30V
