Buying a RR that's had the air box removed due to the front facelift. This has been swapped out for a K&N Filter.

My concern is how this will effect the Secondary Air Injection Pump... If this ceases to function properly then the Cat's will fail prematurely.

Has anyone else had this conversion done and managed to keep the original air box?

Hi Dave,

Guna have to come see you soon after I get this one.

Do you have a seperate filter for the SIA pump? And what do you think about the effect on wading?

Dan 

Quoted from Dave's sig:
"V8 facelift Range Rover Autobiography 22" wheels. "

I don't think Dave worries about wading too often.

(wife thinks I'm nuts - prob right, too)

There should be two cone filters,

One smaller for the pump.

I'm about to tackle this conversion as soon as the painter pulls his finger out with my grill and bumper  TDV8 HST Sport **Current**
