Are these the same kits with just different names and boxes? Seems to be a little difference in prices. On the K&N site, they talk like the kit inclues the spring, needle, and jets, etc, like the Dyno, but in picutes, it does not show the spring. Any feed back would be appreciated. Thanks

 

yes they are the same..for the rincon you get the spring,needle and jets, on my rubicon i didn't get a spring,just needle and jets.it varies with each model..

 

The Dynojet comes with the spring. It is the reason for such a great improvement on low end throttle response for the Rincon.

 

What ever you do, don't get a Dyno-Jet kit. They are a waste of money. They are a horrible design, I wish sombody told me this before I bought one of there kits. I got one for my 400ex and all it came with was a needle, about a dozen "main jets" and an adaptor. No pilots and not even real main jets. Also the jet sizes are further apart making it harder to get it running perfect (if possible). Just today my main jet screw came off the adaptor. Don't make this mistake either buy idividual jets or research into a real kit.

 

There the same. Just buy your jets from your dealer.

 

I ordered a k&n from rockymountain atv and got a dynojet kit. It works fine for me but it would have been a lil cheaper buying individual jets.
