they forgot to put back the air filter snorkel / pipe after last week service..
i was driving it

i notice the engine sound are louder.. and more crispier, pickup are more aggresive than normal. i suspected something, open up engine bay and suprised that the air filter pipe are missing.. call them up and told them this.

last time during my 4g15 carb wira, i used to do open pod intake. the engine sound are crispier than standard drop in.

the technician maybe forgot to put it back.. sheishhhh..!
luckly when i come down there, they treat me very good, apologies & admit the mistake.. if not, sure i'll them kaw2..

this is due to hot air - fuel mixture.. but last time during 4g15 carb.. open pod will cause ur FC suffer!
