Nope VAG parts aren't any cheaper, infact they worked out like £1 more expensive than Seat!

Yeah, It's a larger air intake into the airbox that is used on the seat cupra pd 160 engine.

Does anyone actually have "dyno" proof that this mod makes a difference?

My worry is that although the aperture that allows the air in is larger, the point at which it connects to the airbox looks to be a very similar size.
My argument - how can anymore air get in?

I'm at a sort of halfway house here.

I've had two of the things fitted to re-mapped PD130 TDIs (Ibiza and Fabia) and noticed no difference what so ever.

BUT I'm pretty darned certain that SEAT wouldn't go to the trouble and expense of making it if it didn't do something.

Unless it allows a bit more air into the engine at turbo spool up speed (around 1600-2000rpm) to keep the emissions down????

I've got one ready to fit to my Polo but haven't got round to it yet due to above scepticism. So if someone wants to offer me loads of money for it........... :D

OK here is whsat a guy did in OZ to compare both intakes. Its a bit of reading but in my opinion worth it.

And i dont have the pics so if you have any questions ill try and answer them for you.


Splashed out and got a mannumomtr...manumumeter........ vacuum gauge as I wanted to know what the standard intake was actually like and where improvements could be made.

The points tested were
1. Just behind grill where the intake tube starts
2. Rear end of intake tube just before airbox
3. Top of airbox
4. Turbo side of airflow meter

Then I did several runs, 2nd gear wide open throttle to 6500rpm to get the max reading for each point.

The readings I got (in inches of water) averaged out were

1. 19.5 (bit surprising how high that was! Thats just the air trying to get past the grill into the intake tube)

2. 28.5 (a 10 inch drop from the front to the back of the tube)

3. 29.0 (thats across the air filter - seems like a pretty good filter, not much to be gained there)

4. 44.7 (through the airflow sensor - another big drop. Theres the flow straightening grid, a wire mesh then another plastic grill)



I then fitted the SEAT intake, and after stitches and a blood transfusion, began to test.

You may recall from the first exciting episode, that I had a connection for the vac gauge at the rear of the intake tube, just before the airbox. This is where I connected it for the next set of tests.

With the standard intake I'd had a reading of 28.5.

With the new intake I got 11.2 - pretty pleased!

I then cut away the deflection flap in the intake just behind the grill (see Shanes pics in anther thread).

With this done I got 5.2 !!!! (You were right Shane!)
This was a huge improvement from 28.5

I then measured from the top of the airbox (to get a reading across the filter) and got 7.2 This is pretty damn good for any filter, let alone a stock one. So I dont think there'd be any improvement with an aftermarket filter.

Next was the turbo side of the MAF where I got 23.9
Big frustration, really poorly designed grills in the MAF, but still a hell of a lot better than the 44.7 with the standard inlet.

So, seeing as 44.7 equals about 1.6 psi, with the original intake I was feeding the turbo with air at 13.1psi. With the new inlet, its about 13.9 psi.
And I figure if you're feeding the turbo denser air, its going to do a bit more, despite any limitations of its performance envelope, and this was born out by the dyno results and the Butt-o-meter.

so it's about an 8bhp increase at the peak?

also it sounds like it wasn't the only mod he did.

yes and thats at the wheels

the only other mod he may have is a apr flash, other than that nothing else was added fpr the test.
