Polished up the rocker cover too - wet and dry sandpaper, autosol polish and finished with clear engine enamel to stop it oxidising.

Been driving like this for a few months now. No issues.

Steps were: 1) Rip off all the stock intake. 2) Plug up the Air Suction Valve hole in the head (pipe from the exhaust manifold to the air cleaner). 3) Buy these bits: 1 * 63mm 90degree rubber elbow (attaches to the carb nicely) 1 * 63-75mm (2 1/2" to 3") silicon adaptor - Calibre brand. 1 * Calibre 3" pipe (don't know much more than that) 1 * SCA Pod Filter 1 * Rocker cover breather (not shown in pic) FYI - cut piece of the existing vac hose and mount the breather over the top as they usually have a bigger diameter. Hose clamps. Fit it all. I just strapped the piping to the fuel filter until I come up with a proper bracket. Sounds sweeeeet! You could do it with top $ parts and I'm sure it'll be better than this. I spent less than a K&N filter alone :-) Yes, it's a HAI (hot air intake) but was only meant to be temporary until a weber fits into the budget. Redline auto just sent me this FYI (specifically for 4AFC) - 22680-005 32-36 dgv weber $599.68 inc gst 10-112 adaptor $51.61 inc gst 16-42 air filter $52.25 inc gst 42-21 basic linkage kit $43.77 inc gst

Pod Filter:

Yeah, it's definately the Air Suction Valve. Apparently it allows fresh air into the intake manifold to assist the cat or something, also purges exhaust back into the intake when the exhaust valves are open. I took it all of and ran it with nothing covering the hole, sounded like a tractor! :-) I've now plugged it and all is well. Until I get the weber on I decided to put an intake on the stock carb. Will keep me going for a few months. :-) Sounds sweet and goes good. I didn't really do it for a performance increase, just wanted to get rid of the dog ugly stock intake.

I've found some info at www.autozone.com. Is this the Air Suction Valve? I guess it's attached to the filter base juts to get filtered air instead of unfiltered fresh air?

Hi All, I'm in the process of modifying the intake on my 1991 AE92 4AF (carb) corolla. I started to pull the stock system out and came across some mechanism attached to the air filter housing. It appear to be connected to the cooling system (maybe for cold start assistance etc.) Pic attached. The question is, can I just remove this and assuming it's part of the cooling line just bridge it out completely to maintain coolant flow. I am working towards a 32/36 weber setup. Thanks
