Quote "33-2675 is correct part number for the '96 & '97 model A4. The 33-2125 is only for the 98 & 99 models."<p>And I finally tought that 33-2675 was the right number for my 1.8T 98.5<p>What is the difference between the two ? I already bought the 2675, It seems to fit fine but I just want to make sure, why come out with the 2125 if the 2675 is fine ?<br>

If you want to sell the 33-2675 for a fair price, I will buy it...I actually have<br>another one in my A4 right now...the #33-2550. It is slightly too small...<br>by a very small margin. I got it before K&N officially decided on what size<br>would fit the A4. I think it took Audi to sell 1 million cars before K&N <br>decided to "officially" release one for the A4. Don't get me wrong...I like<br>and have used K&N filters for years.<p>Steve S.<br>97 2.8QM

Per K&N, the air filter for 1998 A4 is 33-2125. This is a new filter, so most places don't have it. Luckly, I live near Riverside, CA, where K&N is located. The following place will sell you one, for a great price, and the can get them within a day. They will do mail orders.<p>J&M speed center<br>909-688-7110, ask to speak to Lisa<br>price $38.95<p><br>Paul N <br>98.5 2.8QMS w/ K&N filter

You could special order it from the following places:<p>1) Pep Boys Auto Stores (I did that once)<br>2) Motorsport One (Mt View, corner of El Camino/Showers Ave...just down from San Antonio)<br> (650-948-2277, I think...it is a new number...old number is 650-367-6666) - ask for Doug or Steve<br>3) Imparts (on the web...very low prices...probably about $39 for that filter...see link below)<p>I need to get one myself now that K&N officially lists the A4 in their catalog...according to them<br>I have the wrong one in my car. :-(<p>Steve S.<br>97 2.8QM<ul><li><a href="http://www.imparts.com">Imparts Web Site</a></li></ul>
