hi,nissan recommends to change air filter every two years in the middle east. I bought my car second hand 2 years ago, with no history of previous air filter change.so my air filter has an age of anywhere between 2 years to 5 years.how can i determine if i need to change the air filter....after following this, im not interested in K&N.
i would like OEM or any other branded air filter that is little better than the OEM at a reasonable price.the two factors that affect me are-a little better horsepower/acceleration-silent car/engine....is there any brand other than OEM, that can benefit me in the above two factors?or else i would be happy going with OEM =)
