Air Filter Review

[EuroAccord13]

Disclaimer : This Test Was Done And Based On Personal Judgements And Opinions. OZ Honda, K&N and Apexi Did Not Endorse This Test....

Ok, The last week, I've been playing around with my two airfilters....

As some might have known, I've decided to buy another K & N Filter to use so I can wash the other filter which came with the K & N Typhoon Intake Kit for the Accord Euro..

A Refresher............



Test Car... My Sexy Euro...



CAI KIT - K & N Typhoon Cold Air Intake



Ok, the difference between the Xtreme Series Filter and the Normal one is that the Xtreme Series has an extra opening on the top of the filter...

One fine night, I decided to pack them up with my tools, go to a nice isolated spot in a friend's farm to test the air filter...

Due to the short distance, I was only able to perform 0-100km/h test..

Anyway, with the Normal K & N Filter, I was able to run consistant 7-7.06seconds and with the Xtreme Series, I was running 7.25-7.39seconds, All tested with the RSM-GP with G Sensor on the very same night with Half a tank of petrol and a passenger.

Anyway, I was curious to how the more expensive filter can kill the time, I did some reading and approached my tuner with the results and findings..

This is what the problem is...

Turbulence...

I've done a CAD drawing to make the explaination easier. See, VTEC engines love air and the faster the air goes in, the better it is for the engine, The problem with the Xtreme Filter is that with the extra opening, the intake of air from the opening creates turbulence in the filter thus slowing the intake charge of the air into the engine. With the normal one, there is no opening and air is thus able to flow more evening in. Having said this, I remembered I once had an Apexi POD before in one of my old rides and it has a cone inside the filter to direct intake air smoothly into the engine. I figured with the cone inside the Apexi POD, it will work better for the VTEC Engines.



If anyone wants to lend me the Apexi filter to try, I would greatly appreciate it as I don't see the point in buying it just for the sake of testing the car. If you are able to lend me the Apexi POD, I will exchange it with my K & N for the time being while I test it to see if my findings makes sense...

Anyway, Thanks for you time...
