i've heard that the 50mm intake mani takes away from the low end. But since i don't have experience with them I'm not 100% sure. good luck with it though.

From what I know of the 50mm...there are two. One for the scirocco and one for the golf. Someone told me - a Golf inlet as the throttle body mounts to it on the left hand side. The Scirocco one looks the same, but the throttle body mounts on the right. Maybe that is why they seem different?

As for performance - again I was told - you really won't feel that great of a difference, but if you got one at a great price, slap it on!

The 50mm will help your engine out in the high RPMs at the cost of a little low end torque. The 50mm really starts to shine when you upgrade your cams.

I'm guessing the other part your talking about would be the throttle body, which is the same part on the 42 and the 50.

Here is an interesting post on the issue. Basically states that uprating the runner size of your manifold is great, but you will still have restrictions with your plenem, your 42mm 2.0l manifold has a larger plenem for teh displacement. If you take the 50mm runners, and mate them to the 42mm plenem, you've got a pretty decent flowing set-up. Just a thought!

It takes balls to cut up a 50mm. That guy is looking for every last little bit. I'm actually trying to get in on his valves and springs.

In reply to Hidro's question... even on a stock 16v the 50mm is almost always worth it, and it will become more worth it as you pile more mods onto your motor. If you're getting it for free in a trade for your 42... DO IT. If you can find another one for that price... tell me. I have like four 42mm intakes in my garage, and no 50mms.

P.S.: It's been super cool watching your English improve from your first posts. You learn a little more with every post... hooray for VW Forum.

DO IT DO IT DO IT!!! If you don't like it I'll ship you another 42mm and you can send me the 50mm.

It will bolt right to your head without flowing.
