does it matter buy a k&n heheh only thing i see is more filter area better flow is not a problem unless u got big v8 like me 3 inch tube for snorke flows plenty of air even with small k&n 5x4 round gets dirty fast but flow under suction of v8 fine 4 cylinder should not see any improvement unless old air filter was plugged anyway interesting probly work great for mud bogging better than pre cleaners plugging up ..lol i'll try it at mud races next time had pre cleaner plug one time and crushed air cleaner eliment and died in middle of run heheh !!
