The factory X51 airbox is A LOT more expensive then any other CAI out there. I'm sure it works better as well since it is a factory piece.

 

I vote for X51. It works like the stock intake as a true cold ram air intake in a sealed box, but more efficient with it's dual openings and filter elements. I got mine for a deal though. I wouldn't have bought it at its current retail price ($3,400.00). If your friend is getting a deal on it I would go that route.

 

3,4000 for a intake??? Thats insane imo

 

Yea it is insane, Porsche increased its price by 300% from its original price. They must have stopped production and have very limited numbers in stock.

 

Momma miaaa 3,400 for a piece of plasticc no offense im sure it looks great and all but idk that number is crazyy

 

To each his own but i have to agree it's completely nuts IMO to spend that on a bolt-on that yield little if any power on its own and is not visible 99.9% of the time. I'm sure it sounds great but so does the EVO.

If you do go EVO, i'd recommend buying the "sock" to go over the filter. My MAF went bad 6 months after the install (3500 miles at install). Who knows if it was poor filtration or just bad luck but I can't help but wonder if the filter alone was up to the task of regulating NYC air.

 

I would have to say, the Porsche's standard Airbox is already a true cold air intake system. The X-51's advantage is the dual filter for increased area of airflow and the questionable CF for reduced temp intake. As for the EVO system, that's not a true CAI system. IMO, he would be better off just getting a BMC drop in filter.

 

My second favorite intake is the stock system with a BMC filter in it. The car actually felt better with that setup over my old EVO intake setup.

 

I think staying stock is a good way to go, but personally I wouldn't use a BMC filter. MAF on these cars are very sensitive to oil contamination and it's a fine line between properly oiled and over oiled. Too little oil and you risk the engine's health.

The EVO can be easily sealed if you're worried about hot air (which I agree is a legit concern). I like the EVo box because I think it's a relatively cheap way to add great sound at WOT. I don't expect any material performance gains from it or any other box.

 

Agreed. I had the BMC filter at one point, and the engine revved more freely from 5k+ onward, compared to before when it was more "choked" up.

 

Agreed with you regarding the oil contamination, but I would just buy another new BMC filter when it came time to change to new one, which is about every 15-20,000 miles according to the manufacturer. This way, I minimized my own fault for over oiling the filter.

I agree that the EVO does sound mean at WOT .

 

Wow i miss 6speed, been spending some time on other forums as well and when u need help/advise or anything nothing com-pairs to the guys on 6speed.. U actually get good lagit answers :} loll anyway thx guys , so im gunna tell him to go for the x-51 esp after everyones opinions.. hes been offered it at like $2800 and the $ isnt a factor so its prob the way to go. U think the x 51 will get a good sound like the evo up at 5k+ ?

 

You think they make a drop in filter for the x-51? that would be better then the one that comes in it??

 

agreed! What do you think about its sound being that you drive with one??
