uni vs twin air???

[400eXr1d3rZ]

I ordered a UNI and recieved a twin air, what is the difference? And it doesnt really look like I would get and extra power from it, it's kinda the same as stock.

nobody can help me?

we do have a powertrain section...

never really tried uni but me/my bro and my good friend all use twin air tand theyre all great. they last a long time too.

uni and twin air are basically the same, foam,and either filter is a good choice. I have a twin air on my KFX and its been a great filter

rejet and take off ur lid and ull get power. all it really is, a stock replacement filter that is alittle more quality made

Then I pretty much bought a peice of crap.

Should have gotten K&N

had one on my ltz worked great!

You didn't get a piece of crap. You got a foam filter. K&N filters are totally different. If you race some MX, a K&N is cool, but if you are going to be anywhere near Water or Mud then you want Foam. Keep in mind its a foam filter, not an exhaust system. How much power were you planning on gaining?

Heh, none. I wanted something less restrictive (foam i guess) and the only way im taking my lid off is if i find an outwear, do they have Twin Air outerwears?

Most XC guys keep the lid on.... Other wise, we would bog done all the time. Its K&N with Prefilter and lid for me.

All you need is an outerwear for an EX. They don't make them based on the filter for foam. Only the K&N's actually use a filter Outerwear. Foams usually just use an outerwear over the Airbox, like a lid.

I found one on Dennis Kirk, thank you!!!!

Outerwear makes one for UNI filters.

As far as filters, there are only two ways to get more power. Bigger filter holes, or a bigger filter. The UNI is a bigger filter. The Twin airs never seemed to do much for power on the applications that I used them. The K&N's I've used showed the most power gains, however the extra dirt in my intake tube pushed me onto UNI's and I've never looked back. One of the best performing (power, and cleaning the air) filters Ive used to date.:D

how often did u clean the k&n?? i clean mine every 3-5 hrs of riding and i have yet to see any dirt in my intake tract. they work great if u keep them clean.

I used to clean it ever 2-3 rides, but after I noticed the dirt it was every ride and it still did it. I used the proper oils and everything. I gave up on K&N for offroad applications. Even if it was an error on cleaning on my part (which I know it wasn't), I still wont use one because my UNI doesn't do it.
