Hi
Thanks for your response. And yepp, you are probably correct. I decided not to make any changes to the air filter right now, due to these odd things HPI put in there, they really don't give a quality impression, if I say so.
In any case, as I am still in break in phase with all the issues mentioned in other threads, I will not add more problems by changing these things.
Once the car is broken in and running fine as it is, I will have a go just to see how it works out.
