OEM air box DE differences between 04 and 06

[Zeezeebaba]

Apologies

 

I've tried the search function but no joy.

I have a 54 plate DE and today purchased an 06 airbox.

The only difference I can see is the size of the "trumpet" in the box.

Is this right please?

Yes...the 06 rev up airbox has the bigger velocity stack inside

Velocity stack

 

Such a grand name for what is essentially a metal trumpet end and mine isn't even attached I need to stick it on with something. Gasket gel maybe.

Oh maybe it's just a standard pre 06 box with a bigger velocity stack placed on top.

But yeah use a high temp silicone to install

[Zeezeebaba]

I've just looked at some pictures of both boxes and it looks like the stack is just an add on to an earlier box. I just need to re - attach mine. It fits in tight but I just wanted to ensure it stays there.

I have an HKS filter to replace the OEM one too.

It's really just the prelude to a plenum spacer as she's already been uprev tuned.

Sounds like you may have my kit in an earlier box.

Just silicone it in with automotive silicone.

Dont use the kitchen stuff as it can affect the MAF sensor

It's in ok I just needed a few dabs of silicone to secure the larger trumpet ring into the smaller one. Unless I already had a later box installed by the previous owner which is also a possibility.It was a nice tight fit.

My guess is that later 06 box has a single larger trumpet.

 

I have Flyboy's conversion fitted, although I silver soldered the new trumpet into the original 04 one, rather than using silicone.

 

It's best unriveted from the box using this method!

I did a search online to look at comparative pictures of the two boxes. Every search I did came back as basically the same box but the 06 one has a larger trumpet section inserted into the existing hole as the seam line can be seen in the pictures I looked at. The larger trumpet on mine slots in tight and held ok without bonding but I put a few dabs of silicone on it just in case.
