Has anyone here replaced their factory intake box and filter with this one (<A HREF="http://www.knfilters.com/search/product.aspx?Prod=57-0596" TARGET="_blank">http://www.knfilters.com/searc...-0596</A>) from K&N?<p>If so, is it worthwhile? Should I expect any meaningful increase in horsepower?

Re: K&N Intake Kit (iansale)

You know, I have been looking at that but I also have seen with my own testing that open element filters are not so good when temps outside go above 85* F, OTOH, one of the most impressive "aftermarket" filters for performance I ever tested was this. <A HREF="http://www.pipercrossdirect.com/viperintakes.asp" TARGET="_blank">http://www.pipercrossdirect.com/viperintakes.asp</A> <br>It doesn't show avl for a R, but I'll bet it's comaptible enough.. these kits are somewhat universal fit anyway. <p>You want an encased filter, add <B>OUTSIDE</B>air coming through a directed channel and your in the bonus. (Provided measures are taken to ensure that water isn't ingested and some kind of basic prefiltering is in place. ...Otherwise, you'll be servicing it left and right to keep it working best. <p><br><BR><BR>

Re: K&N Intake Kit (iansale)

EST has one, better designed for Volvos if that's what you really want. I'm not sure if it really does any good and it has a relly weird sound, not like a usual CAI.<br>One came on the 2000 I sold. We weren't exactly sure what was going on until we opened the hood.<br>Remember unless it's actually piped in from under the bumper, it gets HOT air from underhood heat and in the summer can actually lose HP<br>Under full throttle it sounded OK but at part throttle really weird, almost sounded like something was broken<br>I would focus more on the exhaust and an ECU rather that that, not worth the 300 or so bucks, IMO<br>Buy a K&N drop in filter if you want, takes 1 minute, may get 1 or 2 hp under the right conditions.<br>BYW, wrong forum Ian, belongs in the S&V70 forum. You have a 98, this forum is really for 04 and newer R's, people here have those cars.<br>You may want to ask on Volvospeed.com, the guys there mod these engines and have tried about everything and know what works and what doesn't<br>

Called surge or undershoot. ...real bad and can make turbo go bye bye. Really, to me, this is the real reason why you'd consider this mod. Turbo safety. Then it's only safer if you keep it clean to avoid debris tearing up your turbo blades.

Well, I guess I'm going to forget this mod for now. Dual exhaust is up next, and then perhaps a chip. On JRL's suggestion, I did some digging over at Volvospeed and found a thread with a very similar debate. It's clear that the K&N kit is no silver bullet.

Re: K&N Intake Kit (iansale)

Ian,<br>You have a (wonderful) but higher mileage R.<br>Personally, I would not try to eek out the most hp, who knows what gremlins you could unleash?<br>I would stick with an exhaust (a little extra hp, nice sound) and an <B>ECU</B> which naturally is the biggest bang for the buck, (nearly 30-35hp in itself), a HUGE gain in performance.<br>JRL

Your talking more of a ambient non/low pressure air intake and you changed to a stock airbox with I'm presuming a paper filter so you changed the method of intake and with the word "stock" the filter media which does have a significant impact. <br>So, yes your apple would yield quite a different result than my orange. <br>I agree.<p>Yes, I have years of experience with testing and evaluating air intakes and have spoken with leading automotive tuners about it as well as major auto manufacturing engineers. <p>I diagree with JRL though, I say especially if your taking an older car and making it work harder, you better let help it breathe better even if it's just a panel filter change. What I would accept is perhaps, sure leave stock intake/air box but be sure to change filter media out every 10K miles to maximize efficiency and for ease rather than changing to another filter which have pita factors for maintaining. <p><br><BR><BR>
