Pipercross panel filter

[Yaz]

Hi all!
I just wanted to share this recent upgrade that I did over the weekend as I'm really pleased about it. I purchased the said filter for my A80 Cabrio 2.3, I took out the airbox and made some holes around the wing side of the box to increase airflow. Then fitted the filter, put it all back together and fired it up - the induction sound is phenomenal! The sound of the straight five has been brought to life and I don't need a stereo now!

Thing is this filter cost me less than £35.00 delivered - well worth it I think!

Here's the link to the S2 version, I can get these for a little less than RRP so if anyone wants to take advantage then just contact me:

Many thanks

Hi Yaz, sounds good

Wasn't there something mentioned on here about drilling your airbox being bad for the engine?

Just curious, may think about a new filter actually

Hi mate, I can't see how it would be bad for the engine provided the holes are made in the right place i.e. before the filter and not after it, but i'm sure someone will correct me if i'm wrong...?

Technically there's no difference between what I've done and installing an induction kit. Just in my case I cannot install an induction kit because mine has the fuel lines attached to the top of the airbox.

But you gotta hear it!

I hear you

I love the 5 pot sound, can't get enough of it

I think that would relate to the fact that most "Cold air" intake (CAI) systems that people buy or fab up do not properly shield the intake from engine heat and, as a result, suck warm air (or hot air in the case of turbo system) into the engine, decreasing power because the non-cold air is less dense than cold air and therefore, the ECU does not fuel the engine as much as it matches an air-fuel (mass) ratio. This would be true with holes drilled in an S2/RS2 (or UrS) airbox as well as a cone or mushroom cap filter "CAI".

In this case, Yaz has a non-turbo inline five 10 valve engine in his cabrio (I have actually seen one local to me here in Canada - which is weird because we only got V6 cabrios). If I remember correctly, it has a mechanical injection system, e.g. KE Jetronic and no Mass Airflow Sensor and ECU. As a result, the effect on the fueling and power is probably not as severe. He hears the engine so thinks it is making more power. It probably is making slightly less than stock.

I know this because I swiss-cheesed the airbox on my 1986 Jetta Carat (eventually with a 2L 16V Passat engine) back in 1993. With a K&N panel filter, it sounded great, especially with an aftermarket (Techtonics) exhaust.

Yes I did say the sound of the engine is louder/nicer, but I didn't say it had more power.
The main reason (if not the only reason) why I fitted this filter was for the sound of the engine which in turn for me makes the whole driving experience better. I will be the first to say that a £35 air filter will not give your car more power...

And yes its a K-Jet model

I drilled the airbox on my 10v, sound nice, you get a deep induction note, different from a cone.
