VWR panel filter

Does any one know if fitting of a non paper panel filter such as the VWR one should be declared to insurance, as its not strictly a modification, just replacement of OEM with a better quality product?

....Tricky question, probably depending on the individual insurer. A panel filter itself is a consumable, so, like tyres, I'd say of no interest to the insurer. But I'm only guessing. PM Tony@Greenlight? Or ask him to post an answer here.

It is an odd one, I suppose it might come down to weather it is deemed to affect the performance of the vehicle.... which is probably a little dubious with these filters. My assumption would be that if the manufacturer say 30% increase in airflow, then you would probably only see 10-15% in real-world conditions.
So my peak airflow was 160.78 g/s 10% would be an extra 16 g/s which is an extra 20hp which I find very hard to believe you would get that with a full in-duction kit let alone a new filter! :confused: I suppose my premise could be wrong and the 30% more airflow doesnt equate to a 30% increase in intake air mass......

any non OE change should strictly be declared to the insurers so you are fully covered. :happy2:
you could argue that its a small, hidden (within airbox) part that gives little or no gain so its low risk and prob not an issue if you dont declare.
However if you have other modifications (declared or otherwise) I would expect an insurer to go over you car checking.
We all assess risk in dfiferent ways though, so take the facts, know the rules and make your own judgements.
the restriction for the OE intake isnt just the filter,so the gains for a filter only swap just arent there.
by all means try it but dont expect anything near 20 bhp :signLOL:

Yeah its always best to be sure, and to be honest although I like the idea of increasing the engine air flow, im not worried about performance increase.
And the above calculations were more of a theoretical, and more a skeptical look at a manufacturer claim! If a panel filter was all that was needed to give a KO3 KO4 stock power then everyone would have done it :booty:

....Absolutely right!
I think that an APR Carbonio ram intake attached to the oem box with panel filter barely adds 3 or 4 bhp but they claim more. A remap will help but in my own experience all I felt was a slightly improved throttle response. There may have been an extra 4 or 5 tq but nothing to get excited about.
Improving efficiency is still a beneficial thing to do though.
