    Hey everyone,

    I've made a seperate thread as I haven't seen much mention of the debaffle and golf tee mod, so thought it be some good info for some owners who perhaps don't have or are planning on getting an induction kit but would like a little sound improvement.

    Basically, I'm planning on getting an AFE CAI and a remap for my car but may have to wait up to a month or more, but have heard about the above 2 mods and was hoping some people here knew about it.

    1) Debaffle - So I get this is just removing a little tube from the airbox, which increases the sound of the airbox a bit, but I cannot find instructions on how to do it for an e46 330 anywhere. I don't even know what a baffle looks like? If anyone could help out, that woud be great.

    2) Golf tee Mod - Same as above. I understand that you remove some hose from the exhaust and it keeps the valve in the right exhuast tube open all the time. Again, how do I do this? Are there any downsides to this - I've heard it can harm low end torque? Is this mod reversable?

    3) Drop In filter - Replacement panel filters are actually pretty cheap so I was thinking of dropping one in my standard airbox until I get the CAI - what are the best 2 or 3 dry panel filters? (would like to have 2 or 3 recomendations so I can find something online).




    Cheers guys!

    Thanks Martyn, that is a good link - I've actually found quite a bit of info now, I'm not sure why I was struggling before....

    Really struggling to find anything on the airbox debaffling tho -keep finding instructions for the e36 but nothing for the e46 330!


    Vauxfan - Green cotton filters are dry? Do you have a part number or is there only one type of standard replacement panel filter for the e46 330 for most filter companies? I know AFE do both oiled and dry, but do most others only the one type? I know K&N are oiled, what about BMC and Pipercross?

    Right, this a bit weird. Was out driving this evening and remembered this thread and tried to listen out for a change in the exhaust note above 3k rpm or for the sound of the valve opening and couldn't really hear a difference. My friend refused to look in the exhaust while I revved it, thinking it was some practical joke i was trying to play - tried explaining why wanted her to check, she was having none of it! So ended peering down the exhaust myself when I just got home now, and the valve was open while the engine was running at idle.

    Obviously, can't check whether it closes at revs. I can move the valve by just pushing it, but requires quite a bit of force, and then springs back open. What I find really weird is that the spring load mechanism springs back with quite a bit of force...does the vaccum normally create THAT much pressure??? I could understand if the valve moved and stayed in whatever position I left it in, as I've read with other people, but the fact that it requires so much force to push open either means the spring is loaded that strong OR that the valve is rusted but somehow springs open freely...

    Think I need to check the valve with some revs....

    sounds like its already modded! and yes the force is massive on the spring!, its usually open when car is off, closed at idle and open when you gun it!

    Strange...gonna get someone to have a look while a rev the engine - maybe it's someone what rusted and so closes at once revs are lifted a bit. Have no idea how the vacumm system works, so don't know whether it would be strongest or weakest at idle.

    If it's stongest at idle, then it's safe to assume it's always closed...easiest to look i reckon, if it stays open at revs, i might ask somone to have alook while it's in gear and rolling, as some have suggested this may be required for it to close...

    Gonna open up the airbox and have a little dig around inside, see if I can find anything that looks like the e36 baffle...

    Neal - So my airbox doesn't actually have a "baffle"?

    So does this mean there is no modification I can make short of replacing filters, installing CAIs etc? I know I can desnorkel the airbox but don't wish to do this as it seems to me that this would allow warm air from the engine bay into the airbox.

    About to have a little look inside my airbox now, but I guess there won't be much for me to see!

    Btw - checked the exhaust valve with the help of a mate, seems like it's stuck open -whether it's already modded or there is some type of failure (maybe solenoid has packed in) that has caused the valve to stop working, I'm taking this a nice little stock mod already performed for me!

    I'm curious as to what the car would sound like with the valve closed - I did notice the car had a nice deep rumble, but assumed this was normal, I didn't notice a difference from a couple of other 330's I test drove during my search, so maybe it isn't a massive difference...saying that, I do like the way my car sounds, so would recomend this to anyone who has a valve that does currently close itself!
