Weapon-R Secret Weapon Intake (301-175-101)
I cant remember who on here had one of these installed, so I caved in and created this thread.
Question of the day for everyone is .... how did you guys install the included Breather Filter? And question 2, what are the effects for NOT running said Breather Filter?

Bonus Question:
How did you guys route the Ram Air Kit tubing?

Disclosure: This is based on past experience with older Hondas. I am not familiar with the PCV system on the Fit or aftermarket intakes for the Fit.
Evil, did you connect the tube from the intake to the valve cover? The crankcase ventilation system needs clean air in, which it pulls from the intake tube BEFORE the throttle body. On the other side, a line runs from crankcase to the intake manifold, which is where the dirty crank case air (from blow by) is pulled back into the combustion chamber to get "cleaned out." See this chart here that explains it. The PCV valve is a one way valve that keeps stuff from going the opposite direction. The breather filter would go on the line that goes from the intake manifold to the crankcase. You would remove the tube, and put the breather filter on the crank side, so when pressure builds it is expelled out of the filter instead of being fed back into the intake manifold. In reality it's just going to mess up how things run, because the ECU thinks it is getting additional air from there. I would not use the breather filter. It's more of a race application thing, and even then, i would use an oil catch can, not a breather filter.
Another dumb thing I see people do (well dumb in my opinion) is to install the breather filter on the valve cover inlet for the PCV system. In this case instead of pulling clean air from the intake tube, it is pulled straight through the filter. That is just for looks, and if you had a hole on your intake tube for that, now you have a vacuum leak if you don't plug it.

Presently, my intake is all stock. I've been insanely lazy with my mods as of late .... its all just piling up
I'm in full agreement, and I think I will skip the breather altogether. I dont like the idea of losing pressure and letting anything vent to atmosphere. But ... for kicks & giggles ... I did ask how the breather should be installed and here is their response:

It would be redundant. Either the catch can or the breather attaches to the PCV valve.
#12
BD, i meant using both. Connect catch can to PCV and then instead of connecting other end to intake, you install breather. So catch can is still removing oil, and then the positive pressure is discharged out through the filter, instead of into the intake manifold. That's how it works in my head at least.

On a daily driver/street car, catch cans are usually connected to vacuum to assist in removing the pressure from the crank case. It also vents the fumes back into the intake, so there is no oil/fuel odor, or residue.

so after much debate and endless sleepless nights ... I decided to go for a traditional install. no breathers, nothing fancy
prior to this weapon r intake, my setup was oem + k&n drop in filter + sumole ram duct scoop thingee. IAT's were about 10 degrees over outside temps. it would appear, the weapon r secret weapon sri has similar iat's

Nice pics! The IAT info is nice to know as well. Glad you like it.

thanks Myxalplyx. you're just the guy I needed to speak to. your custom intake/box/scoop setup was just too awesome. I wanted to ask ya for some advice, I plan on running the secret weapon ram air tube/duct. any thoughts on where I can mount the duct and route the tubing?

That's exactly what I was getting at. Highly suggest finding a way to mitigate water inlet though... Also if you're serious about it making much of a difference don't use the provided accordion tube. Get some silicone tubing.
