Benefits of cold air intake
#21
how can they draw in cooler air from on top of the engine? while our stock air box pulls it from behind the headlight as cool air is rushing in?
unless done properly, theyre warm air intakes imo. not even close to being worth the $300 they ask for them. I see it being less restrictive as the only upside, which is hardly worth what they ask. **emphasis added**

as per the link i gave early on, what is being called a CAI more often than not now is nothing more than an exposed cone filter. unless you add the heat sheild which acts as a directional air box, you are sucking hot air. also in the link given is the explaination of how a CAI works in theory:
Increasing the diameter of the air intake, reducing airflow velocity and pumping losses.
Smoothing the interior of the intake to reduce air resistance.
Providing a more direct route to the air intake by eliminating muffling devices.
Shortening the length of the intake.
Using a less restrictive air filter, usually trading filtering quality for increased airflow capacity.
at the end of the day if you are looking at a $300 cai you might be aiming a bit too high. unless you are hung up on a name, a whole kit can be had for like $50, then get a replacement filter (k&n, spectre, etc) by preference for like $30 more. take the time to build your heat shield and AT MOST you are out $100 even after buying a pair of K&N stickers to slap on it...

Nice job on that heat shield, man!

you answer your own question. you have to use a CAI correctly. you have to isolate your filter (which sits in almost the same spot behind the headlight anyway) from the engine. this can be done as easily as installing your own piece of sheet metal.

^^^ what ?
#26
well, as we all know hot air rises so im still not sold. a cold air intake would be taking air from outside the engine compartment imo. either ram air (stock) or else below under the engine like the tuners do.
and still, are you going to notice the claimed 5hp and 1mpg? for the 1-300 bucks?
you can get a running 5.7 for around that

then dont get one
#28
You can get someone to custom Fab. a eprom chip for your ECU and adjust the air/ fuel ratios adding either horse or mpg and adjust the fuel/air ratios for various temperatures as well. Plus a conversion completion will cost 8 times that amount of a cold air intake.

Nice thread bump BTW.

None-The engine compartment is hotter than the normal intake. For less restricted air flow get a K&N replacement filter.
