1st Mod : K&N Air Filter

K&N Filter in place of the original filter

A sticker to warn of the "motorsport" element inside

The car was relatively new when i put K&N filter in, it only clocked 25,000 km to its record. I must say, everything was normal with the standard air filter. The filter is sufficient with normal style driving. 

However, on highway or at high speeds, the car lacks pushing power, especially when the IMA won't really be assisting at high rpms, the car felt like its "out of breath".

By putting the K&N filter in (part no. 33-2433), the engine behavior drastically changed :

1. Acceleration is more pronounce even from slower speeds. At middle to higher rpms, the car felt "eager" to move.

2. VTEC sounded more livelier this time. Passing 4,500rpm the car surges forward with a loud "praaaang" sound.

3. FC wise, not much different if the driving style is normal, however, with high speed pushings, the fc may drop to as low as 16km/l.

One of the benefits of K&N is that its washable. It's cotton media must be washed with a proprietor cleaner kit from K&N and its relatively easy to do.

Thanks to K&N, now i have committed a traffic offence.
