Hi
Just joined today and hope I am posting in the right area

I have a 1,8 Tigra and the air intake tube has 2 baffles .The 1.4 has 1 baffle and the diesel has none
Just replaced mine with the diesel tube as cheap from a scrapyard . My thinking is a direct airflow should give best MPG and power?
Am I totally wrong?

All exact same and went in perfect,

Any reason why there are baffles on the petrol engine tube and none on diesel

They are not baffles, they are resonator tubes. They are there to reduce intake (induction) noise.

Oh ok , So it will be little more noisy ? Is that all? No gains from having direct airflow
Thank you for the reply

No gains whatsoever. The tubes are there to try and counter resonance pulses on ⛽ petrol engines. Diesels effectively run at full throttle so do not have the same issue.
