I dropping my RS off for a full service tomorrow,and I thinking of having them put a K&N air filter while Its there.I just installed
a staintune pipe a month ago,so I thought with a new tune this would be good combination. heres the catch the service manger and one of the techs says theres no advantage over the stock filter.
Will I see a difference with the K&N,, or are they idiots?

There is a bit of disagreement on this. When I asked my dealer about K&N's both he and his head tech. opened up a new K&N and a stock fliter and laid them both cut open side by side. I've stuck with the stocker as they proved to me that it was a better filter.

I had K&N on my car and truck and observed a more dirty film down stream from the filter than the stockers had and went back to stockers on those two.

From what I've seen on honest dyno runs you won't see any difference there either as the whole system is highly tuned to begin with.

I know others swear by them but I've seen more potential damage and very little gains for me to think they were worthwhile.

I tried to put a K&N on my Sprint and it was not an exact fit. I did not use it.

After seeing the OEM on my 1050, the K&N went on. There is no question it flows more air by just looking at the 2 filters side by side. My dyno proves it as well. I use K&N on all my cars as well, and some of them have 150,000+ miles.

i would stick with the stock filter. Just ask your self why K&N flows more air ? has to be less filtering ability IMO. Which is going to let in more particials of dirt.

If you want a K&N to fit your '02 RS, I have one new in the box I'm not using. PM me if you're interested...

I put a K&N on my ZR7 and noticed a significant difference. I've never put one on my Triumphs because everyone says not to.

So, is the concensus with the K&N that yes, it's more free flowing but it blocks less debris and grime? If that's indeed the case I'm disappointed. You'd think there would be more technology working with the K&N than simply being 1/2 the air filter it should be.

Thanks,

I personally like K&N, I have one in my car, and it works great. I had one in my old Honda VF100F, My wife has one in her VFR800. They have always been good for us. I noticed my Honda ran much better with the K&N in it, old carberated bike, ran a bit rich with the K&N but much smoother.

When my air filter needs replacing it will be with a K&N.

I don't know about K&N's letting through more debris and grime, but I do know they work in a different way to normal paper filters as they use oil to attract the dirt and hold it in the filter material (cotton I think). Whilst the paper ones rely on just being a finer mesh which means they can get blocked quicker than K&N's. So it's not a case of K&N's (and other similar aftermarket filters) having less filtration so that air passes through at a higher rate.

I've installed K&N's into cars and seen a big difference and I have a BMC filter in my sv650 which has made a difference but I think the major improvement on that bike was not the type of filter but the airbox mod - i.e the tank was lifted with spacers to allow greater airflow and the hole on the top of the airbox is about twice the size of the stock version so there is probably twice as much filter surface area available and I presume twice as much air available to the carbs. Of course with that set up the carbs had to be rejetted...


my other 2 cents...

My son & I did the same mod to his 03 SV650 which is injected. It runs great, just ask the guy on the Supersport with the "screaming eagle package" that got his ass kicked by a 650 :hammer:

I have always sworn by K&N filters in cars and had one in my 03' V-Rod with fantastic results mated with a arhinehart exhaust. Never put one in any of my Triumph sport bikes simply because of having to remove the tank. Since my bike is at the dealer now having the TOR exhaust installed I asked My mechanic (who has built a few drag bikes) what he thought of adding a K&N filter. He said there is now a third Triumph download available that will fully utilize the higher airflow with the free flowing exhaust. He has installed two so far ; one on a Sprint 1050 and one on a new Speed Triple 1050. The S3 dyno run showed almost 10 hp gain and nearly 3 ft. lbs trq. He said on the Sprint it definatly "woke" the bike up gave a little better sound to the TOR than on the other bikes he's done. Will let you guys know when I pick it up this week. Now just wondering if I should just go ahead and do the 18t sprocket while it's there or wait and get an honest veiw of how this works out.

Keo,
If I understand you correctly, you're saying that there is a tune that is specific for the TOR+filter?
Please post the tune # if you have this done!
Thanks!

Having used K&Ns for years on my dirt bikes I can't see that streets would even begin to tax their filtration capability. No stock map (TOR or otherwise) allowed my bike to run correctly with a K&N and a Staintune on it. But that combination with a custom map bummped me from 103 RWHP to 114. YMMV, but there's three sides to every coin...

I put a K&N on my '00 ST 2 months ago. I didn't notice any dramatic change in rev or sound. I like the K&N because I can refresh the filter whenever I want without spending $35-$40 on a new paper filter each time. I also added a dab of white lithium grease inside the airbox, down stream of the filter. I'll check it this spring. If the grease has dirt on it, I'll go back to paper filters.

There is no factory tune for an aftermarket filter and TOR pipe.

factory tunes are:

stock w/air injection
stock w/o air injection
TOR pipe with air injection
TOR pipe w/o air injection

Stiles,
According to my mechanic at Triumph of North Ga. ( Steve Studstill) my bike now has the 5th download available from Triumph. Download # is 20126.

TOR + K&N air filter

If you have any questions call Steve at 770-740-7519

All I can tell you is the bike fells a good bit stronger and I love the sound. Not opressive but a little more growl.

Interesting.

20126 is Brazil only Tiger 1050 with after market exhaust.
20118 is the equivalent tune for Sprint 1050.

www.tuneboy.com.au/TuneDownloads/Tunes.html

I wonder what's different about Brazil? And shouldn't the new Tiger use the '07 ECU with doubled memory? If so, I would not expect that tune to load in an '05/'06 ECU.

The plot thickens...
I notice the tune numbers and titles are listed on the above site but the download links to the newer files either don't work or you are sent an older version (20104~20107) file.

Anyway I would think you should have received 20106 unless they blocked SAI and removed the precat from the header, then 20107.
