Hey guys im new to the forums. I have a 06 scion and i was wondering what is the difference from a CAI and a short ram intake. Which one would be a better pick for me. Thanks.

 

i say secret weapon r for a short ram and injen for a cold air. i would go for the cold air cause it gets cold air since the filter is located at the bottom unlike the short ram where it's at the top next to the engine and it's recirculating all the heat from the inside.

 

Stupid question, does the CAI still have that nice sound to it?

 

to me it's louder on a stick than auto, injen and fujita do that hissing sound, for auto you have to go over 3k to hear the sound well.

 

I drive a stick so thats good to hear. Thanks for your help.

 

injen converts from cold air to short ram
go for injen
good product and if you go with cai..get bypass valve just in case
you dont wanna hydro-lock

 

there have been numerous threads on this "cai vs sri" topic. cai gives you a tiiiiiiny bit more power, nothing you can feel though. it's also harder to install than the cai, since its longer. it also has a bigger chance to hydrolock your engine . but, the sound is a lot nicer, which is usually why people buy it.

 

Go with the Injen Cai, reasons being what streetstarstc said. Anyways its nice because it's really mid/high end kinda, like you don't hear the sound at all time when your driving.

 

Okay i decided to buy a Injen CAI. Should i also buy the bypass valve? I dont think im going to be driving in like crazy ___ weather conditions

 

Thats like a really big debate here, you have a choice of a bypass valves or an Injen repellent cone cover thing (I can't recall the name). The thing is to hydrolock you need to submerged in water, but when your submerged in water and have a bypass valve, its still going to hydrolock. Maybe its just me because I'm from Cali and it doesn't rain as hard here haha thats why I'm not so worried, but you know what, its better to be safe than sorry, its a $20 investment right?

Oh yeah, does anyone know if he bypass valve restrict airflow, I know it might, but I doubt its a big difference.

Whats kind of scary is when I look at my engine, my intake piping has water spots on them haha @_@

 

ya but it only takes a little water in your engine to create catostrophic failure, water will not compress in your motor and any water may cause a stress fracture in a rod etc, and over time it will eventually fail and throw a rod etc.....It happend with my GT-S i never fully hydrolocked it but water got in and i mean not even a lot when i pulled the plugs like nothing came out when i turned it over....It does not take much to cause failure guys...

 

could someone give me sites to where I would get a bypass valve?

I have no issue with my CAI but every time there's a little puddle, I avoid it! Is that the only way to avoid hydrolocking and how deep in water until..?

 

AEM is the one who makes those bypass valves for about $45, just make sure you order the correct size.

 

check trdsparks.com you might have to do some modifying i think?
