Gti6 intake manifold

[Tidoh2016]

I have a 1.8 16v engine in my 306 and have been offered a gti6 intake manifold for it. Will I gain anything by fitting it? Is it worth getting the having it gas flowed properly?

Never mind just found the guide

Hi. I've done this mod on the 1.8. you'll need the gaskets and senors and the air box setup or just a filter for the end. You'll also need to sort a breather out.

It doesn't add much. Maybe a few hp but it does make it sound better.

It worked for me but many have said it didn't run right after.
