    Cold air intake?

    Some of my friends with Japanese cars are slightly obsessed with engine mods such as a cold air intake. I was thinking that the 505's air intake is really sitting right on top of the engine so it must be sucking in hot air.

    Has anyone ever bothered to try fitting some sort of cold air intake on a 504/505? I don't mean a K&N cone filter, just a pipe running from the front of the car up to the air filter housing. I was thinking the hot air box attachment would make it very easy to fit a hose to the filter housing.

    Is it worth trying this (or at least wait til summer ) or just let it be?

    This 505 (from Chile) seems to have a different air filter setup which takes the air from the front of the car:

    The STIs had a cold air setup which sucked from above the radiator. The metal plate that sits between the radiator and the grille (across the top) has a hole in it, and a fitting mounted to take an air duct to the intake.

    I imagine you could find one of these plates quite easily from a wrecked STI, and with some flexible ducting plumb from the inlet to your air filter.

    I have on in my garage (holed plate & inlet fitting), and could mail it to you if you want (but I bet you could find one in Melb.)

    Alternatively, GTIs sucked cold air from the driver's side of the radiator, and on some cars (including my STI) there is still a second opening there (in front of the radiator, to the side) to which a duct could be attached. The Chilean car you picture looks like it might be using that inlet.

    Bear in mind your GR might actually have a heated inlet manifold, in which case cold air will do precious little good.

    I thought about the same thing and was actually consider a K&N for my 504Ti. Seems that the intake is actually pretty good for the standard setup (oil bath filter type), all you need to do is change the oil in a normal service and clean it with petrol rather than buy a new filter cover each time. Plus the intake hose sits in front of the radiator. The only question I have is why is the mouth facing the side of the car instead of curving to the front. I guess you'd get a lot more crap in the filter and maybe more servicing needed but isn't that a pretty good price to pay for more air?

    It's also intersting to note that the rubber intake hose has a metal trumpet piece in the mouth for better flow. It's amazing they went to all that trouble for such a tiny curve radius - must make a lot of difference.

    Bagel, I don't have an oil bath filter. My car is pictured below (I appologise for how dusty it is in the pic, it had just been bush bashing!)

    Gus, I think you are right about it being heated. There is a smallish rubber hose running off those pulse air valves (?) to the back of the filter housing.

    I've always wondered why it was red.

    Interesting.

    Nick,

    Go down to your local auto parts shop and grab a can of Carbie Cleaner, take the air cleaner hose off and give all over the carbie a good go with it *including down the throats*

    Cheers

    I'm sticking a newer carb on it this week so I think it will be ok

    I've never noticed a petrol smell so maybe it used to leak and was fixed up before I bought the car?

    If I were you Nick, I'd give the new carbie a good clean up before u put it on, just for good measure...

    After all a can of Carbie Cleaner is only around $8!

    504's with a similar airfilter set-up came fitted with an "automatic" cold / warm air "diverter valve" mounted on the front of the air filter body , Nick. Many people took them off because they rattled, and looking at the picture I find myself wondering whether yours might have originally had one too.

    If the carby has never been cleaned since new, then after 20 years it will be very dirty, regardless of how well it seals.

    You really need to clean the outside of them atleast once a year, just like the rest of the engine.

    Well I have the 'new' one sitting on my desk at the moment. It is far less dirty than my old one, but still a bit grubby. Should I just spray some degreaser on it and give it a quick scrub? I guess I should make sure the degreaser can't get in any of the places were the numerous hoses connect .

    Yes it did. The previous owners had taken it off. It is sitting in the garage somewhere...

    Just wipe the outside with a rag soaked with solvent (e.g. paint thinners, acetone, etc). Make sure you wear gloves. This brings the carby up like new.
