Only if cold air talaga ang intake.
Imagine this, naka racing filter (k&n, apexi, etc), kaso nasa engine bay naman. Hot air intake na siya kasi hot air lang mahihigop niya instead of cold air (in slow moving or super traffic situations). Pero if mga 80kph pataas na takbo, the cold air coming through the front grills will feed the air intake cold air. (Measured this thru the MAF temp sensor - got one of those obd gauge).
And take note if hot air intake, parang sakal ang acceleration. Dapat talaga cold air intake, palit exhaust system and remap to get the best results.
Ako gusto ko lang tunog. 😆
