Performance Testing The DNA Air Filter And Cover On The Royal Enfield Hunter 350

The DNA air filter and cover set up is easy to fit but is it really worth the money as a performance upgrade?
In this video I performance test the standard and DNA set up in a third gear, 30 to 50mph roll on test using the Dragy GPS performance meter to measure the results.

I also tried to measure the induction noise, because the DNA filter is louder in this respect than the standard filter. That was a less successful test...

And finally, as part of the exhaust downpipe test, the air filters were retested to see if there really was making a 0.45s difference between the two set ups.

My conclusion? If you're looking to pep up your Hunter just a little, the air filter is an easy to fit upgrade. The down side is that extra induction noise... Either way, with standard or DNA filter, the Royal Enfield Hunter is a cracking little bike.
