With good marketing, people will buy anything.

 

Intakes are hard to test strapped to a dyno . IMO

 

There is a simple answer to this dilemma

Winter times when there is cold weather = Throw your cone intakes or CIA on
Hot weather = Throw your stock intake back on
Nuff said.

 

Are you willing to dispute Dinan's numbers on their CAI or are you just saying that a display of shiny marketing material will typically yield more sales? If the latter, yeah, there seems to be a pattern there.

 

So in cold weather climates do the CAIs actually do something noticeable?

 

Noticeable performance wise no, Noticeable sound yes.

Some cars do react better to intakes than others, but even the best gains you wont actually feel a difference. You will gain a few horsepower most likely less than 10bhp, which means 6Whp, which isnt much at all. those that say they FEEL a difference just hear the sound and placebo effect kicks in and they think they feel a difference. If you run the 1/4 mile at 14.25 an intake will get you to 14.20 or less of a difference, which isnt noticeable at all.

 

Even if my intake gives 5-10hp, the sound is addicting and worth the mere $60 I paid for it.

 

^ that is the exact reason to get one.

+ it does a lil engine bay dress up.

 

So does anyone have a used one they don't want anymore? Send me a pm, I'd love to try one out.

 

ive got the Dinan intake thats pictured in this thread w/ dual RPi scoops....its literally worth it for the asthetics alone! lol (see the attached pic of my car).



but seriously tho, i have a few performance mods so i dont know which ones are the total game changer but i eat other 545i and 550i for breakfast anytime i see one.....and its far better when im on the freeway and have 75mph of cold air being optimized by those RPi scoops.

i say if you are thinking about this mod, pull the trigger! (but only after an aftermarket tune....and exhaust....and throttle body....*cough* Dinan *cough* )
