Vantage Air Filter Options
Discussion
I'm looking at changing my air filters and wondered if anyone has swapped out the OEMs for the various options out there ?
I know you can buy:
1) OEM app. £50 a pair
2) K&N Air filters (PN CM-4508) App. £120 for a pair
3) GT4 style app. £480 a pair (With removal of air boxes etc)
I know there are quite a few threads discussing the pro's and con's of each, but really wanted to know if anyone has actually swapped and noticed a difference.
Any information would be appreciated.

If we assume that the pair of filters are about £50 (absolute max....), then the labour is app. £350.
Based on AM charge rates, that's about 2.5 hours labour.
They must be employing the slowest screw removal guy in the world.
From the workshop manual:
x5 screws for the wheel arch liner
x3 torx head screws liner to under tray
x7 self tappers for the air box base
No wonder AM have just announced pre-tax profits for the first quarter at those prices.............

Intake filters are easy to change, but take a while due to packaging.

As for options: typical dealership pricing in the US is ~140 GBP for a pair of OEM intake filters, and actual cost is higher than 50 GBP so I'm not sure where that number came from for price (price *per* filter, maybe?).
A lot of people swear by oiled filters, saying there's no risk from the oil contaminating the MAF sensors UNLESS the filters are over-oiled. That's the problem - they can get over-oiled. I've got some dry ones in development right now. High flow like an oiled filter, but without the oil.
I don't have air boxes on my grey Vantage. I've been testing adapters and filter safety and, so long as the guy that designed/produced them is open to it, I'll be selling them. There are risks associated with removing air boxes, but we all have different thresholds for what is acceptable. So remove the air boxes at your own risk.

Funny....my car (V8V) is going in for service soon. AM dealership came back with quote and a add-on in case the air filters needed changing.
£395 for air filter changing!!
Don't mind paying the first quote but I have a feeling ill be discussing the 395 with them!
They really have started to take the mick here. Websites list this as an additional £284 'bolt on' for a V12 http://www.dicklovett.co.uk/aston-martin/servicing...£395 for air filter changing!!
Don't mind paying the first quote but I have a feeling ill be discussing the 395 with them!
To appraise the filters and see if they need changing as part of the standard paid for service the dealer would have to access and open the air boxes. Closing them back up with new filters should NOT cost £284 or £395. My Indie charged £98 inc VAT for this bolt on (V12)...
Pattern (prob same Fram make as OE)? £50 for 2
OE £105 https://astonmartinbits.com/models/7-Rapide/parts/...
Make a living not a killing!

I took the price from a good UK non AM supplier here, £40 plus VAT and P&P, see below (NOTE: These are not OEM) Apologies for mistake:http://www.redpants.lol/intake-filter-change/

I'd be happy to remove the air boxes as I believe the biggest issue/concern would be water ingress. However, I dont go out in the wet much, and even if I did, then I have seen other threads discussing driving in the wet with no problems.
I'm testing the risk on my own car. Looking at how well the filters stay in place, how much they get exposed to water, and drivability concerns.
I'm using OEM filters on my grey car without air boxes. I have a Vantage GT4 front bumper fascia on the car, so there are brake cooling duct inlets at the front of the car - but haven't run the ducting yet, so they're pointed right next to the exposed filters. In the last week, I've hit triple-digit speeds and driven through light rain and wet roads (and got splashed with mud by a dump truck) and haven't had any issues at all with drivability. I'll be digging into the car this weekend to see if the filters are still securely in place and how much damage (if any) they've taken. If the filters do well during this testing, they'll be fine for just about anyone - I'm putting them through more than most people would ever consider with their own cars.
The one concern that will remain regardless is if you drive through water deep enough to submerge the filters. Water will flow through *extremely* quickly if using cloth filters (dry or oiled, doesn't matter). The water will be much slower if you have paper filters, so it's somewhat safer in this instance. I've got a rather controversial video showing this:

Have you made up some bracketry to fix the non air boxed filters into position (As per David Appleby GT4 style air filter option) ?
I can't see the justification in their price if its a couple brackets/ducting etc.
I could get these fabricated and fitted myself as a little side project.

Yeah, using adapter brackets. A ton of work is going into making sure everything is perfect and secure. Once the air box is gone, there's nothing holding the filter in place - the air box cover does that in the factory setup. So if you get filters and an adapter that aren't all exact, you risk the filter wiggling loose while driving due to all the movements of the car and constant vibrations from the road.
Great video Rich - always like your matter of fact not 'all around the houses' approach.
I'd personally be very wary of messing about with filtration on a 'keeper'? A bit of oil/water on the MAF would be a major pain beyond a little power gain?
Just one question - Merlot or Cab Sav in that great glass!
Keep em coming - it's appreciated (esp given the end b price of £50 air filters)

I must fit 10 air filters a week to all sorts of cars and the usual cost is a tenner so it always seemed a bit strong that a pair for a db9 are £100.
just got a pair for £20 +vat !! , local Andrew pages branch , "Blue Print" part no; ADJ132232 listed for DB9 specifically (theres 2 in the box), blue print is part of Bilstein and ive been using their parts for about ten years always perfect fit and excellent quality.
might be wrong think there same as vantage

I'd be careful with super-cheap filters. You may get lucky and be perfectly fine, but it's a topic of concern for me. Our cars are extremely sensitive to imbalances in airflow going into each MAF sensor. If one side flows more than the other, you'll get an "Emissions System Warning" CEL and pulling the fault codes will show an issue with MAF sensor correlation. A loose filter can cause that CEL or, even worse, allow unfiltered air into your engine.
I've been working on a set of high-flow filters for a while now and it's been a full engineering effort, not just a "here are the dimensions" specification that I took with a measuring tape and sent off to have made. There's been a lot of testing on the OEM filters, including fitment within the air box, to make sure everything is perfect. We're still several weeks from being done, but I think the value proposition is worthwhile given the quality.
And that was probably probably a cab sav if I remember correctly

Much appreciated!! It's been a long time since I've posted a video - lots going on, and I'm learning to use all new equipment (new camera, full lighting setup, playing around with audio). Should be back to uploading this weekend.I'd personally be very wary of messing about with filtration on a 'keeper'? A bit of oil/water on the MAF would be a major pain beyond a little power gain?

I'd be interested when you've got it done as to comparing with the OEM and others.I've been working on a set of high-flow filters for a while now and it's been a full engineering effort, not just a "here are the dimensions" specification that I took with a measuring tape and sent off to have made.

What kind of testing?
This kind?
