They are also their incase your engine back fires some of the pressure has a plce to go without blowing off intake hoses alot of cars have these but different design
If those are indeed resonant chambers (if they are hollow inside), they will serve to reduce induction noise. The general rule is to get the as close to the capacity of the engine to balance out resonance. Have a look at Lexus and how Yamaha tuned their intake to completely silence the car. The volume of the resonant chambers is exactly the same as the capacity as the engine and this is achieved through the use of multiple resonant chambers, some close to the intake and some further down the track closer to the filter and even some pre-filter. The different locations no doubt help cancel out the different Hz at different loads and rpms. I don't know if the ones closer to the intake cancel the high Hz or low Hz. Removing the ones furthest from the intake pre-filter revealed that idle can be felt and smoothness at idle deteriorated. Removing middle one revealed no difference at low-load but increased mid-range roar at full-throttle idle to red-line sweep. I have not removed the one closest to the intake. Using this logic we can conclude that the resonant chamber is to reduce noise however I can't say at what parameter (Hz, load, rpm etc.) as these are very small volume and very close to the intake. Personally, if you wanted the full intake induction roar, all resonant chambers should be removed. I would also agree that removing them would also smooth the air-flow path. If anything, making the chambers bigger would simply reduce intake resonance generally. I do suspect that Maserati kept them as minimal as possible to keep the intake roar but cancel out the V8 rumble from the cross-plane crank design as much as feasible while still keeping the roar.
These bulbs are no longer available on amazon. I've bought similar that are canbus error free, but I've got error on both sides with these bulbs. Could you please let me know how to attach a transistor and which one. Do I have to attach it to both sides of the bulb terminals or where? Thanks
I think it needs to be combined with upgraded air intake too, to make the sound deeper. Perhaps little difference can be felt in 4.7 qp or Granturizmo with oval exhaust, but on 4.2 it'll definitely be a deeper growl...
I watched this video over several times, just hoping that I could convince myself that there was some difference. Man, they sound exactly the same. That sucks.
I found them going for a reasonable price in eBay but like everyone else here despite the affordable price, it was hard, however not impossible, to perceive the difference. Couple of Questions my friends, (And of course I have one of these cars it's why I'm even here) what are these things originally for? (What do they actually do?) and What would happen if they were removed completely?
they are there to producing more deep throttle rev. it is not a significant difference just slightly. is it worth the money? it's all depending on you and how you love your car and like to mod here and there. personally, i like the way it looks than the OEM, secondly, I just feel its slightly deep throttle in the cabinet. So its all depend. hope that help. The truth, is i do not get any commission so i am not asking you to click here or punch the keyword. its a user to a user
Why would anyone replace those with larger ones??? I would immediately remove the stock ones and cap the ends. Those “sound chambers” do nothing but rob airflow..
