Yeah my K&N is much better than that snorkel. lol
If you want performance velocity stack is the way to go, and the more surface area on your filter.. the easier it flows. Common sense I guess
Some of the craziest tuning Ive seen on included CNC intakes, CNC polished carb inlet, custom billet CNC velocity stack, dial a jet, and massive oversized foam filters. Velocity length influences the power band on thumpers. short for top end power I think
and longer for bottom end.. someplace in between for a balance is what you want.
Ive always thought 2 layer foam filters are the best for high end performance but I don't really have any proof.. only weak anecdotal evidence.
Some engines also like a "step" inside the intake I don't know why but it works well with some thumpers. Rough intake ports help with fuel atomization so even if you port it out leaving it rough keeps things flowing and prevents drip.
For 2 stroke foam filters are amazing.. especially if they get a little wet with gas.
For the savage I think the airbox is a pile of crap lol. A tuned velocity stack and oversized filter would be much better than that rubber intake boot with a cone filter. I see some dudes on here with those chinchongyoulicklongdingdong china fleabay filters.. dear god those are crap.. you can see right through the filer mesh.. Ive used one on a small engine and it only filters out birds and small babys.. Also you can throw on one of those mesh covers to help prevent water/rain from pulling dirt into the filter. Pretty sweet I think lol
I'm just rambling..
