Air Filter

[rs4boy]

Chaps what do you think is the best panel air filter for our cars, done a search can't find much about which one to go for.
Thanks

Keep it OEM IMHO!

But I'm sure I have read various debates on here, with alot of discussion!

I'd rather stick to OEM, purely not wanting to risk anything for the sake of a few HP's, and sacrifice filtering quality

Just my 2p's!

Hengst are apparently the equivalent of OEM spec filters.
Euro Car Parts sell them for under a tenner.

Hardly any difference between ECP prices and OEM Audi.

Or if you don't want to buy from Audi, then go to GSF and get the Mann item they do which is the same as Audi

Forget the panel filter replacement. Waste of time in my opinion.
I have fitted a few BMC CDA. Not cheap but is an improvement over factory.

Any of those nasty wooshing sounds from the DV's with the BMC CDA filter system? Not my cup of tea !

Looks like a tidy mod if you look on their website around €270 delivered...

Have seen these alot in the VAG scene, but still not totally smitten, or proven to me that they do work, or more importantly are better than a panel filter.

A BMC CDA an improvement over factory RS4? You're kidding, I've dynoed personally 3 cars that LOST 15 to 20 BHP with BMC CDA vs. stock.

[Virdee Autos]

I'm sure Audi spent enough time and money on the RS4 intake/airbox, hence why its an improvement over the S4.

Each to their own, but I've seen the prices of the BMC, and even if it does offer negligable gains, the price out weighs it

I think the power LOSS dramatically outweighs any price argument. In case you didn't read my previous post correctly: 3 remapped RS4s consistently LOST 15 to 20 crank BHP after having BMC CDA fitted. After removing those airboxes and refitting stock, remapped power was back to where it should have always been. I also had logs where the air flow was correlated to the loss of power (15g/s less flow with BMC CDA fitted).

[Virdee Autos]

I'm in absolute agreement with you Minhea.

Incase I didn't state it properly. but what I was trying to say is that the cost of the BMC is so high, that even "IF" it does offer any improvement (which it doesn't according to your experience/facts), it just doesn't make sense....to me anyway!

[boxerdogted]

As they say all noise and no go.

[mattykerby01]

Stock filter for me !

[rs4boy]

That it then stock it is, just like to no about these thing.
Thanks chaps
