My Prius v (lowercase v) Mods

Sometimes I wish I lived in another state that is less strict like yours. I have a feeling the intake would pass the performance portion of the test. I'm pretty sure that they'd get one on the visual inspection portion. I have a K&N intake on a '99 GS400, and when I took it to get smogged the one guy was nudging the other, I think to fail me, for a darn K&N prefilter I had put on! I have the EO sticker in plain view right next to the intake!

I have to agree that the cotton gauge filters do a good enough job from my own use/research.

Just curious, did you see a carbon element somewhere in the stock intake, or is it built into the filter element? I was under the impression that the carbon element was separate.

 

Definitely don't cut into the stock filter. It would be a waste. Like I said I thought it was a separate element altogether. Should be easy enough to see, one would think, just looking at pictures of filters on the net, if it is part of a single filter. I'll hopefully get some time to search filters later.

The tester can fail you here just by seeing an aftermarket part without a CARB EO#. It is sad, but partly a money making thing here I guess. I didn't know that is what the carbon is for. Thank you.

MT2L03 ?

 

cool

 

So I was looking into purchasing a replacement air filter and got to see some pictures. I can't see any type of "carbon" on the aftermarket replacements on AutoZone or O'Reilly. Strange, but if the carbon is in the filter, then these aftermarket filters would not be CARB compliant! I ended up purchasing a aFe 31-10228 Pro Dry S but am thinking it may not be compliant. (Maybe should have just gone with the Injen intake!)

 

It wasn't too hard to find an example of the hydrocarbon filter from a Toyota. A modification to remove it to improve performance can be found here (I honestly don't know why it takes me a while to figure out things, ie. in this case it took me days to figure to do a Google search on "hydrocarbon filter"):

Toyota 4Runner Hydrocarbon filter removal

Here is a picture of the actual filter from that same page:

The page notes that "H C" is stamped on the top half of the airbox, and the carbon element is attached permanent style to the top. I honestly don't remember seeing this "H C" on the Prius v box anywhere, shown on this picture from that same page:

http://www.top4runners.com/cgi-bin/image.pl?/ja/2007/hcf/hcf7.jpg

The example vehicle is a 2007 4Runner 4.7L V8...

The hydrocarbon filter seems to be a separate more permanent part of the air filter housing. From the looks of the 4Runner V8 setup, it is on the engine side of the housing, meaning the hydrocarbon filter would go on the inside of the conical filter of the intake.

Maybe I shouldn't have rushed to buy the aFe filter if there is no hydrocarbon element in the Prius v and could have hope for a CARB EO# for the Injen Intake, although I don't see them show the dyno results...

 

Never mind. I just looked over the installation instructions for the Injen Intake from their website. In one picture you can clearly see the "H C" stamping on the top half of the airbox just as they show removing it.

It is on Figure 6....

 

Hey Eric "v" did you ever replace the stock shocks on your "v"? I know you did exhaust tip, but did you do tuned muffler or exhaust system? I love your "v", building mine on what I learned from your set -up. Looking for adjustable Shocks and Exhaust muffler for my silver zvw40 2012 v m5. Anyone else have their 2 cents on modifying "v"? I love My little v......

 

The smog check station could fail you on the visual inspection without a CARB EO#. No "sniffer" test necessary. I wish it were so simple...

We have to be careful not to assume that our smog check experience translates from state to state. Some states and even areas within states have no smog checks or different ones.

 

Yup. Should have specified for California only. My apologies.

e.g. Vashon Island is exempt from King County/WA's smog test

 

NY State just instituted tint testing at annual safety/emissions inspection: > 70% transmissivity (< 30% tint)

 

Here's some photos of an HPS CAI that I installed a few months ago. I really like the sound and added thrust that it provides.
YMMV
Happy Driving!!

 

Nice! Did it affect your fuel economy in any way?

 

Did you add the stickers for their incremental 10BRWHP?

 

How hard was the install? I did this on my first car and I remember loving the sound too!

 

The install was pretty straight-forward and took about 25 minutes. You may need an long (>12") ratchet
extension to get some of the 10mm bolts removed. Regarding gas mileage, it seems to have improved
slightly, but I do seem to be heavier on the gas pedal now that it sounds so "throaty".
