Hey, I recently installed a short ram intake into my GS300. I didn't run into any problems except that the new intake only had 2 inlets (for EVAP hosing etc), while the old one had 3. Would it be ok if I took the hosing coming off the engine (I'm guessing crank case) and the hosing coming from the EVAP unit (I'm guessing its the one that vacuums out the gas fumes) and put them into a T joint connected to the intake? I figured that the 3rd, larger gauge, hose coming off the throttle body would need its own inlet. Would this cause any problems?

Thanks in advance,
Ellis

 

yes.........

 

So nothing bad will happen like fuel vapors getting into the crankcase or anything?

 

No.................................

 

Ok. I don't know much EVAP hosing and stuff like that. Thanks

 

though rare but possible, the only code you will throw is a Lean code.

 

Would that be caused by the fact that the intake is getting more air, causing it to lean out, or would it be due to the hosing configuration?

 

Air and ECU not being able to compensate. like i said rare on a 2J GS3, but possible. Its mainly a problem with the GS4 when going with a Intake without management/piggyback.

 

Ah ok. You seem really knowledgeable about these kinds of things so maybe you could answer another question. Is the duct that is above the radiator there because that area is a low air pressure zone, which makes it easier for the stock intake to suck in air? Or is it there to physically pick up and force air into the stock intake. I ask this because I left it in place with my ram intake, thinking that it physically picks up air and that it would force it into the area where the filter is.

 

leaving it is the correct way of doing it, it brings cool air into the intake while driving.

 

What for to you this "cold" intake? From it there will be no any power increase, only air will heat more strongly. Money for a wind.
From ready products there is nothing better a stock intake ..

 

So leaving the scoop there will force air into the area of the new intake, giving it more air to suck up? And I mainly did it for the sound qphoton.

 

First, the most part of hot air will take underhood,
Secondly, aluminum piping underhood will heat up air also ...
The regular intake with a box for the filter is made of the plastic providing good thermoisolation, besides it is tight and takes away air from street. Instead of the regular filter it is possible to put K&N with smaller resistance, but even it won't give you any notable power increase.
