2nd link not working. apa la... b20 wei... somemore with HV sticker so maybe done at HV. If rumours saying HV no longer doing vtec, which means this car become limited edition
I plan to go with S90 @ 70mm throttle body and aftermarket aluminium intake manifold to match with my Deratech cam.
Meanwhile, is upgrade on air flow meter is necessary?
If needed, what is the air flow code number is good to upgrade?
Also, changing in bigger air flow meter will make the engine run lean ?
Please advise and educate... Thx.
