Default 2008 accord v6 very poor performance

Hello everyone


I just bought a 2008 Honda accord coupe v6 auto


the car performance is poor I tested 0-100 KM/H and it took 11 seconds !!!

The car has a K&N air intake system other than that fully stock

What can I do to bring back the performance

The air filter is not dirty ( I just replaced it )

the car idles fine and it's smooth but acceleration is the problem

What do you think ?

Suggest checking catalytic converter for excess backpressure. This can cause terrible performance and poor gas mileage. Search youtube for numerous testing examples. Following is one of the best:


good luck

Clean the intake and lose the K&N in favor of a factory intake.
