  2. PH1 TS Intake hose and resonator replacement

    Alfa GTV & 916 Spider
    The intake hose attached to the throttle body was splitting and I fancied replacing this with silicone pipe and also replacing the resonator box. The pipe needs to have a 15mm connection for the crank case breather, and looking on ebay I found one of these...

  4. Air filter resonator

    Alfa 147, 156 & GT
    Can someone tell me where the air filter resonator is and what it looks like? '04 156 JTD. What is the likelihood that it could be damaged by running the drivers side up a kerb at speed? I had extensive undercarriage damage repaired under an insurance claim. However the car isn't running right...

  6. Replacing Catalytic converter with Resonator

    Alfa 147, 156 & GT
    Hey, Tomorrow I'm off to get the Cat removed from my car. Will get a resonator fitted (no emissions testing here in nz).

  7. Resonator in or out?

    Tuning & Upgrades
    I currently have the airbox and intake pipework off my GTV in bits to fix all the rounded off, or snapped studs. Anyway, when it all goes back on, will my 2.0 GTV benefit from the resonator being blanked off? If so, how much? And am I going to have to glass fibre the entry hole, or is there a...
  8. V6 Resonator Box?

    Tuning & Upgrades
    Hi All What is the function of the upper resonator box on the V6 and does it have any detrimental effects on the performance/airflow? Has anyone ever tried replacing it with a straight thru pipe? Just a thought, I appologise if I'm covering earlier threads. :D

  11. How do you remove the 16v resonator box(Selespeed)

    Alfa 147, 156 & GT
    I have been playing about for a while. I have managed to remove the air ducting to the air filter box, detatch the air filter box from the resonator box, and now cannot get the resonator out of the car. The self tapping screw which holds the air intake pipe to the main body of the resonator is...
  12. Resonator Box

    Alfa 164 & 166
    A popular mod on 156 Twin sparks appears to be the removal of the resonator box on the inake system to improve throttle response, replaced with the intake pipe from the V6. Does removal of this box improve the V6 too. assuming the pipe can be replaced with something suitable? I was under the...

    General Alfa Discussion
    If that's it's right name, the box right at the bottom of the air box, now I know 888dee and Paul (and no doubt other's of you too) said take it out. But surely alfa designed it and put it there for a reason, I mean they must spend million's developing car's it cant just be for fun, they must...

  15. Resonator Removal 156

    Alfa 147, 156 & GT

  16. Took off my resonator

    Alfa 147, 156 & GT
    Hey all, On a whim, after reading posts by Ulf on his new Novitec exhaust system (and seeing his pics) and researching other crazy Japanses guys who have done up their 147's I have decided to take off the big main resonator under the car. It's a massive muffler in the middle of the car and...
