Hello,

I have a K&N filter in the genuine air filter box, but the noise is very present in the car under acceleration

Is it normal ?

The car always got this filter since 10 years / 10.000 kilométers (I'm from France)

I clean the filter but it is still noisy.

 

Any advice please ?

Are all the clips present which hold the 2 parts of the airbox together?

[eric.sen]

Yes all the 4 clips are there and the 3 screws also

But very Noisy Under acceleration actually

How have you diagnosed the problem to be the filter ??

What type of noise is it ?

How different does it sound to a Blown exaust or manifold leak ??

Are there any other symptoms ?

Is the car running well ?

[jamesquintin]

Has the noise started since you put the K&N filter in the housing or has it become noisy over time?

 

I found one of my exhaust bolts on the head was loose causing a lot of noice, could be that? also make sure filter housing is flat and secure

Hello Nu2mini and Jamesquintin

 

Maybe you are wright because I didn't notice that noise before,

 

But the noise is only Under full acceleration

 

I know that I had to repair the braided part Under the manifold just before the Cat.

 

If the braided part is used could it be that noise ?

install the old filter and see if it is the same. If not, then it's the filter. The K&N replacement filter is a little noisier, but shouldn't be too much.

Yes I will try to found my old genuine air filter.

Look to the car today, the bolts to the manifold and the head are OK and the filter box also....

Some news....

I had a sump guard, took it off, it was doing resonance chamber,

now the car under acceleration is lot quiet.
