Does anyone know of an aftermkt fresh air kit for the '04 Legacy 2.5L? It seems one hasn't been offered or I don't know where to look (more likely).

 

It could be that a universal kit would do, but I don't want a cobbled together piece of junk, nor do I want a bling-bling high $ piece. I just want a better, less restricted, intake which = better mileage and a little more hp.

 

Thanks in advance!!!

On non-turbo engines the stock intake is not restrictive enough to cause a problem. If there were better mileage to be had with a different intake then the engineer's would have made the change.

 

That is why they aren't offered. Also there isn't a lot of money in aftermarket parts for N/A engines. The name of the game with Subaru is Turbo Charged AWD. Most people find out quick that they either just want a car that gets them from point A to point B or they want something they can tinker with - which means a turbo.

 

You should be able to find a MAF adaptor for a cone filter. It will make the engine louder, but you won't increase HP or mileage to speak of.

+1 to what GD said.

 

Ebay sells kits you can copy those. You can also buy the rubber connectors and pipe and make your own.

 

Some filters are also not as efficient and require oiled filters which can contaminate the MAF sensor wires if that's the style sensor it has, not sure about all EJ's, maybe some are MAP?

 

There's little to be gained. You might *think* or *feel* better about some mod's but realistically speaking you're not gaining anything. So depends what you want - novelty and *feel* or a real world car that moves, has dyno and quarter mile times that show it.

 

Should be some info, pictures and such on here, ebay, and NASIOC, it's been done plenty of times before.

Your air intake should already have a scoop that runs over the top of the upper radiator support so it is pulling in fresh, cold air. If you put in a standard aftermarket intake, it will most likely have a cone airfilter inside the engine bay, with warm air that's already been through the radiator, or a cone airfilter inside the wheel well, just waiting for a deep enough puddle to hydrolock your motor.
