Installing a Velocity AP GT4 Airbox Delete Kit in an Aston Martin DB9

[@erepsekahs]

These are far superior videos to the normal run-of-the-mill postings I see from other 'enthusiasts.' What I particularly like, (and I am sure this is true for everyone), is that you take time to discuss the 'why' of what you are doing as well as all the how to. This is incredibly important to understanding the process, not just in this but in every 'how to' you provide. I just wasted my time this morning with another video from another well-meaning individual concerning the repair of the leather coverings of the dash-board. That video included a, "I'm not going to bother to show you that" cut-away, and no clear decision on which of all the products he actually used after trying them. One had to re-run the video to guess which one it was. Thank you so much. I am most fortunate to find you, however youtube has now stopped anyone collecting a library of useful videos.

Black Friday at VelocityAP right now, and I just picked up a 2014 Vanquish. This video is still very relevant today. Excellent job.

Steve, I am not sure about the whole air box removal idea but I appreciate your care and attention, great videos. Thanks for sharing.

[@melvinthaddeus2943]

You probably dont care but does any of you know of a trick to log back into an instagram account? I somehow lost the password. I love any help you can offer me.

@Melvin Thaddeus instablaster :)

[@melvinthaddeus2943]

@Jaxon Heath thanks so much for your reply. I got to the site thru google and I'm waiting for the hacking stuff now. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.

[@melvinthaddeus2943]

@Jaxon Heath It worked and I actually got access to my account again. I am so happy:D Thank you so much, you saved my ass !

[@jaxonheath3038]

@Melvin Thaddeus happy to help :D

[@johnchambers1250]

Great job, considering this myself, can't wait to see the dyno pull

[@Aston1936]

The Dyno pull will publish tomorrow! Thanks for watching.

[@mstock3107]

Thanks for the great info Steve I just did this on my 07 Vantage not sure I would have figured out all the steps without your video

[@Aston1936]

Cool, glad to know it helped on the Vantage too!

[@mstock3107]

@@Aston1936 I also just put in the velocity clutch my next move is the cat delete from them in your video you did not mention programing with the cat delete is there any?

[@jacobsessum607]

Do you know of anyone still producing this kit or similar, dony see it from AP..thanks great video!

[@bladerunner6282]

dimensions of modern airboxes are designed with the aid of complex mathematics coupled with a number of engine performance factors and a massive amount of testing. the displacement of an airbox and the velocity of the air within it and its internal shape that determine air velocity all work together to meet the engineer's goals. it's also clear that the manufacturer (and i suspect they simply threw together a couple of common aftermarket fancy chromed air cleaners available at your local walmart together with a couple of ill-fitting zip-ties and two crude cradles, put it all in a box and called it a kit) never even attempted to install it on a DB9 as evidenced by the zip ties that don't fit. and BTW if you're worried about the money, with a little research you'll find that those same filters, sans logo, can be had for about 20 bucks apiece.

... throw in couple so so engineered brackets that will start cracking and they charge $260 for it

[@mediabybrendan2654]

I love the videos Steve! I'd be a little hesitant to carry this out. Given the positioning of the filter and lack of an airbox, I see there being a risk of sucking up water if you drive in a rainstorm. I do like that the air down there should be cold, but I don't think it's worth risking the hydrolock. Although I'm sure you never drive it in the rain./

[@Aston1936]

A fair point to be sure, although the design of the original airbox and the ram air inlet still directly allow water laden air to blow directly onto the OEM paper elements without an intervening baffle, so the risk is likely the same unless we are talking about submerging into 12" of water, and then the airbox would keep the wave of water out. In California I am definitely not fording any streams with it. Thanks for watching!

[@Andreasz4]

Great video, like always :) How did it sound after the replacement? Brgds, Owner of 2308

[@Aston1936]

Interesting that you should ask about the Sound. I think you can actually hear some 'Snarl' from the engine up front now as its sucking. When I full throttle accelerate, its notably more aggressive sounding from up front. Kinda cool.

[@ckjlgp]

Hey steve, another great video, will you be doing a video on servicing the gearbox?

[@GB9Garage]

Steve, would you recommend these now after using them for a while? I think they are on backorder but just curious what your thoughts are.

[@HarryESwan]

Do you think it was worth it? Mike over at Bamford has some kind of airbox upgrade for my VSV8 but i can't get a hold of him, and i have tried many times.

[@OverlandTT]

I've run k&n panels just about all my life. I wonder if you've seen prefect farms test in them. I found it alarming and it concerns me regarding the longevity of my Cayenne V8 and obviously for a future DB9...

[@sierraone9181]

Excellent

[@chiefexecutive]

Thinking about ordering this for my vantage… hmm

[@fabriziocristiani9630]

I would know, the same kit is avaible for the vantage v8?

[@nbjornberg8259]

thumbs up!

[@robertthrailkill1368]

One recent place where my DB9 lost some performance were at the PCV ports on rear of intake manifolds. The right side is capped off and only the left side has vent pipe. Aston used a truly crummy design here that is very prone to leaking and falling apart. This let’s unfiltered air into the rear intake manifold robbing rear 1-2 cylinders of fuel. The plug on right manifold fell out on my DB9. after ingesting the small rubber washer and car ran really rough and surging and smoking as computer kept dumping more fuel into the engine. The port has a pressed in brass bushing with a 5mm gap behind it with flange at rear. There is a washer in that gap that is held in place by a plastic cylinder that fits into the brass ring. Into this goes a plastic plug on right and PCV pipe on left that press fit thru the washer to create the air tight seal. This is all held in place by little metal bards imbedded into the plastic retainer that is inside the brass bushing. Holy Crap what a dumb ass way of doing this. The washer cooks in the manifold till it falls apart and gets ingested by the engine. Now there is a poor seal. Eventually the plastic plug vibrates out of the metal barns and it leak even more and falls out all together. If you find any play in these fittings then they are leaking air into the intake manifold. Check yours, I bet they wobble and leak air. That makes the rear cylinders lean mixture which is a bad thing for power and predetination . Aston does have a repair kit for $60

[@68akhan]

Where can I visit your shop?

[@cruiseoveride]

Wow. Literally a zip tie solution to something someone spent millions engineering. Not for me thanks. Keep up the great videos!

[@Aston1936]

Fair point that's not lost on me. Its reversible, so I am playing around a bit.

[@japanesevintagecarschicago]

Puts cheap pep boys filters on an expensive car. Lol.
