Open Pod Air Filter Comparison

Hi guys!

In today's post, i would like to share some comparison done by Revspeed magazine Japan. Nowadays a lot petrolheads change their stock airbox to open pod air filter. But the question is that which one is the best in flowing as much air as possible, without sacrificing filtration efficiency. The article compares for most popular kits available which are HKS, Apexi, Blitz and K&N.

Important Notes regarding the comparison:

1. Extracts of this article have been transcribed from a Japanese article featured in Revspeed Magazine, August 1999.
2. The original test was based upon the results found when using filters specifically made to fit the Toyota Supra. However, the filtration is unlikely to differ, as all the filtration materials used are the same for every model of car.
3. The cost given for the filters are based on a the kit for an R33 Skyline GTR, except the K & N kit which only currently exists for a Skyline GTS, and are inclusive of VAT.

From the comparison, we can see that Apexi Power Intake wins the test in both filtration and power gains. But for me it is still questionable since the HKS are proven to sell more in the market if compare with others induction kit. I think the battle is futile. So the question still stands, "Which Induction Kit is the best?". You can accept the result from the test then the Apexi Power Intake is the winner but if you are still skeptical don't worry as the performance gains are quite the same =)

My Big Bro's Ride

Hi guys.

In today's post i would like to write about my brother's car. It is Toyota Corolla AE101. Pictures below.






Powered by 4AGE 1.6L 20 valves 4-throttle engine design by Toyota and Yamaha. This engine is well known for its ability on track and also touge. This engine in stock form can scream up to 8000 Rpm. The sound it makes during high rev is totally sweeeeeeet! This is the 5th generation 4AGE engine produced from 1995 to 1998 is the final version of the 4AGE engine and has black cam covers. This engine is fondly known as the "black top", and yet again features an even higher compression ratio (11:1), the air flow sensor is replaced with a MAP sensor, the diameter of the four individual throttle bodies was increased from 42 mm to 45 mm, the exhaust port diameter was increased, the intake cam lift was increased from 7.9 mm to 8.2 mm and the intake ports were significantly improved in shape, contour and also the width at opening at the head was increased. This revision increased the power to 165 PS (163 hp/121 kW) at 7800 rpm with 162 N·m (119 ft·lbf) at 5200 rpm of torque. Usually we can find this engine in Corolla Levin / Trueno , Sprinter Marino and Carina GT.

Some modifications to the engine are:

• + Custom 4 Throttle Trumpets
