Title: Installed K&N drop in with restrictor ring.
Post by: flynlo on April 02, 2009, 06:52:46 PM
I finally installed my new K&N air filter drop in with the restrictor ring and the longer screws that come with it. Pretty easy but i didnt take the gas tank off, just removed two screws and propped it up enough to get a shorty philips head screwdriver in there....its always the last screw thats a pain in the ass....why is this? Murphy's Freekin' Law ..? I hate that Murphy guy...anyway....It sounds pretty good, a drop louder i think....and i could swear there's like 1-2 more HP..or is this
in my brain like a "placebo" affect...you know like adding a sticker adds 5 HP or something like that....anyone ever notice this?   I am correct that no re-jetting is necessary, yes? It seemed to run fine afterwards.

Cars are supposed to have 3% HP gain from these filters, why not a bike right?

Glad to hear!!  You should be fine with the restrictor installed...though the GS is a bit lean from the factory so it never hurts to rejet a bit

I run hare scrambles on a 450R and I can tell the difference in HP when the filter gets dirty.  So I wouldn't doubt it if you do notice a bit extra oomph. 

But as for the sticker thing, cmon man, stickers suck.  Even if I had the baddest car / bike / atv around, I wouldn't advertise it.

Dude stickers make it go faster!  I mean a NOS sticker on a Civic will take at least 1 sec off of your 0-60, and as an added benefit you will suddenly become attractive to women...  :wink:

Anyway, Flynlo how old was the paper filter?  You might be getting getting an hp boost, as Hawk996 suggested, because of a cleaner filter.  I would think it wouldn't just be the filter because that would mean you would have more airflow which the point of the restrictor is to prevent.  I cars probably get a small boost straight away because with fuel injection they can tweak the fuel for the amount of air and carbs don't until you rejet.

I did the same thing, propped the tank up and took the filter out with a shorty screwdriver.  None of my screws were obstructed or hard to remove.  I didn't have a wiring anchor on one of the screws like the manual says.  What a stupid place to anchor wiring.

I have a K&N filter in my Neon.  Didn't change the mileage or increase power.  I think it's an economy move more than anything else.  You can wash it, spray it, and put it back in rather than buying filters.
