There was an old thread a while back about airfilters for an E63.. Any one know how much they would increase the HP ? would you feel a difference in the early acceleration ?
Thx

Am sure it is a very slight gain if any.

So I guess it is probably not worth the update ?

I think anything that 'gains' is worth it depending on the price. That is a very small gain with a very small price. Large gains tend to come with large prices.

Personally I think it is a no-brainer and would do it immediately if it were my E63.

Are you talking about removing charcoal filter? I was thinking to do the same, but I am not sure about the consequences. There must be reason MB put them there. Anyone knows what the risk is? What about warranty issues?

We have a 530hp kit for the 63... On the dyno, it showed a solid 24rwhp.

We sell the kit for $749.

Albert,

The filter is for emissions only , to meet laws here in the USA. They are not on Euro spec cars. Taking them out allows better air flow and can increase hp. This is free and all it takes is a torx screw driver.

The VRP filters are high quality and added a few hp. The kit definately shows gains and I dynoed at a shop independant of VRP. My best previous dyno with tuned ECU was 408 and I hit 440 with the VRP 530 and , Evotech ecu.

I would say 12-24hp gains....

AlbertM

What does the kit consist of?

Thanks, I live in NY (Long Island), does anyone know a reputable shop that can install this properly?

1 up on that question. I'm interested.

AlbertM

If all I want to do is remove the charcoal filters, do I need to replace the stock air filters with HiFlow filters or can I leave them in? and if I do, what can I expect in terms of HP gains just from charcoal filter removal?

It seems that removing charcoal filters is a fairly straight forward process, but will the car fail the inspection or emission test?

AlbertM

Ok, removed the charcoal filters today, I dont see any noticable difference, should I put them back??

Very difficult to notice it from butt dyno, need before and after at the track.

Its about 10 hp and you wont notice it . The more air you get through that box the more HP your car makes. The stock filteris restrictive but it works and the car is better off w/o the emissions charcoal. My car has 17k miles has been to the dealer a few times and nobody cares the filters are gone

Since the 63 is N/A you are not going to get huge gains from anything until you get more air flow.
