Default k&n 77 or a 63 series

Other than the chrome pipe, what are the other differences? Which is the best choice for a 08 ram 1500 hemi?

Hey man I asked the same question about a month agoand everyone one here helped me out a
lot! So I feel obligated to do the same:

Thesis- The 63 Series is way better than the 77;It stays cooler and provides more HP -

The K&N 77
[ul][*]Provides An Additional 8.34 Horsepower At 5392 Rpm[*]Is a strong conductor of heat[*]Not as wide as the 63 (not as much mass can pass through efficiently)[/ul]
The K&N 63
[ul][*]Gives 10.49 Horsepower At 5445 Rpm[*]Is made of a non-metallic, heat resistanttube[*]Costs the same as the 77[/ul]

The 63

You forgot to mention that the 77 is at least twice as loud. I love mine.

Yea, I have the 77, it REALLY echoes the EGR valve sound. Go with the 63...
