Customer Feedback

Hi Friends,

I have a Bajaj Pulsar DTS-i 150cc, 2004 model.

Before I used to get a top speed out of my bike of approx 115 km/hr and an amazing milleage of 50-55km/lr (speed 45-55km/hr) and on the highway it would be of 65-70 km/lr (Speed 50-60km/hr). Believe it or not that's true. Now thanks to the K & N air filter, it not only boosted the power of my bike but my milleage also got high and the bike sounds like a thunder storm.

After some unique upgrade in my bike with the help of K & N air filters & NGK spark plugs I get pulsating power + mind blowing millage.

Now my bike unbelievably reaches from 0 to 6 in less then 4.5sec. I got a top speed of 140km/hr.(as shown in the speedometer) and my millage after this upgrade is 53-58km/lr (speed 45-55km/hr) and that on the high way of 68-72 km/lr (Speed 50-60km/hr).

The max milleage that I got was of 78km/lr (Speed 50-60km/hr) and the top speed of 140km/hr, was on the Pune - Banglore highway with a single driver.

Believe it guys it's TRUE.

I have a Bajaj Pulsar 180 cc bike and I changed air filter to K&N RC-1060. I have 52.1 km/Ltr mileage, more performance and more speed.
Now I am so happy.

Hi All,
I have a Bajaj Pulsar 150, old model. It used to give me awesome pickup and mileage at the same time when it was new. The bike got older and mileage reduced, so I installed RC-1060 Air filter from K&N. The pick up of my bike became amazing and I can really feel the back thrust. The bike gives now while accelerating. Mileage increased too. Good work K&N. Now I will look up for more K&N accessories for my bike.

Thanks K&N.
