most probably after install open pod, top speed will reduce unless do a full tune via piggyback.

i already have that mushroom setup... ive never been a fan of HKS SPF filters...came with the car when i bought it though... hence the thought of changing. thought of putting in the apexi dual funnel power intake or blitz sus... so thought about changing air ram one shot.

believe it or not...in my old B16A had some RM50 chapalang open pod.... tried the ori HKS SPF... few days.. changed back to the chapalang with a big smile on my face.

if that setup gives better low-mid range response then thats good..... coz vtecs has pretty much sucky torque in that range...i myself have a torque dip between 3.5-5.5 according to my dyno chart. so i guess ANY form of improvement in that range should be a good one

then buy my TYC laaaaaaaaaaaaaaaaaaaaaa hahhahahaha


thanks...are there any disadvantages for vtec engines?

top speed will reduce for sure because Perodua Alza ussing K&N open port and last time with original can go 160kmh easy now liter bit hard need longer road.

but overall power upgrade u can fell the car lighter ..



but how fast u want to driver every day ?

to me low RPM power is important becuase the car use 80% in town and 20% on highway.

Thinking of using drop in K&N air filter on my myvi ride..but read on the K&N thread say after using this drop in /open pod need to reflash back the ECU.is it true?

no need to reflash... been using it with so much fun...

Beware of imitation air filter in the market . However , imitation onces can also be use . No significant differences anyway .
