Perrin or rcm are the main tried and tested ones.

Best thing for that hks mushroom filter is to burn it

 

 

Cause it doesn't filter :-)

 

Very poor filtration and bad for the MAF sensor

 

Heard horror stories about the ram air too,bits of foam being sucked into the turbo!

 

Imagine the damage the particles do to the turbine blades when they are spinning at 1000's of RPM per second.

 

Just replace with one of these as your car is mapped to this type of setup

There’s a few that do the enclosed kit as this so there’s less engine bay heat getting soaked by the filter




I think my mate has one in the pics above for sale but not 100% sure

 

HKS= damaged compressor blades
Trev

 

You are running a top mount so throw a filter into the wing. Go K&N they get really good reviews but I'm surprised no one has mentioned going back to the original airbox with panel filter.

 

I'd say keep the original. Just put a Cosworth or K&N in there. Job done. If you want more induction noise then take out the snorkel in the wing behind the wheel arch liner

 

 

 

 

Will do

 

Removing the snorkel will decrease the "hopper effect" that collects large particles and stops them from entering the air filter box.
