Hi everyone. I own a Linea 1.3 MJD Emotion Pk and in six months have run it for about 12,400 kms. Now I am thinking of installing the K&N stock replacement Air Filter. The rate that I've got from an authorised dealer is Rs. 5200/-. Advantages:- 1. Increases acceleration. Increases power by about 2-3 HP. (K&N claims as there is increased air flow and better filtration). Hardly noticeable IMO. 2. Higher fuel efficiency. (K&N claims as there is increased air flow and better filtration). 3. Refined sound (engine clutter). 4. It is eco-friendly as its not a paper filter and has cotton gauze. 5. K&N filters are washable and reusable. They serve the engine for about 50,000 kms in one wash, unlike paper filters that demand replacement every 15,000 kms. 6. The famous "Million Mile Limited Warranty" by K&N. Disadvantages:- 1. Its expensive as compared to our OE paper air filters. But, with K&N its just a one time thing. Can't really think of any other disadvantage as such. Rain in your suggestions and advice people. Folks who've installed K&N air filter or intake system or oil filter to please pitch in and throw some light on this. As after the air filter I am going to opt for the K&N wrench off oil filter also. Cheers.
