i just came into some extra moeny and have dont the air box mod but am thinking of getting a injen intake. has anyone went from the air box mod to an aftermarket intake and those who have whats the difference. when i did my air box mod i just took the bottom off so without the rest of the box it will obviously whine alittle louder but what about performacne ??

chris

 

yes.
there is no performance difference.
only a nicer sound and prettier to look at.

 

so with $250 what could i buy that is a better investment i have a hurst short throw, gm performance exhaust, and a 3.15" pulley

 

CUSTOM 2.5" exhaust. The GMPP exhaust is a 2.25" design.

Numbers in my sig are with the airbox mod

 

Catless downpipe or a header id say.

 

i'm gonna get a check engine light though because i want to go catless and no one around has hp tuners

bump

 

I disagree, I went from air box mod to injen, I think there is a gain over the mod. However, at this point no one has any dyno proof. Our dyno day is coming soon and im going to try it out.

 

Injen Ftww!!

 

I want dyno proof before i shell out 200 bucks for something that may give me 1 more horsepower

 

Onyx Bro. Injen Gives U Power. U Can Run Anyones Car With A Before And After. Its Goona Be More Hp Anywhere From 5 To 7hp

 

i went from the airbox mod to a cai. can't tell the difference "seat of the pants" wise at all. the sc does sound much better now though

 

Large claims. Prove it. Show me some dyno's

 

i can prove it with basic logic.

Cold air intakes give power based on 2 things.

1 is a rerouting of the engine air intake location to a cooler area


hmmmm no luck there. already a CAI from the factory, no change in routing. bubbye HP gains.

2 is using a higher flow filter than normally stock restrictive paper ones.


sorry, airbox mod has that too.


so umm.....where is the gain coming from?
the "sexyness" of the injen pipe?



sorry, but an aftermarket CAI does 2 things.
look good.
sound loud.

other than that, a dropin high performance filter, with the removal of the airbox restrictions, will match its gains 1:1.

(btw, how is it possible to show "gains" of 5hp, when a car can dyno with differences of 10-20hp with no changes)

 

Ill Get Dynos =]

 

I have been through many intakes, and airbox, imo its all the same ****, one just a tad louder than the other.

 

They have dynos that Injen is a proven to increase hp and it also helps acceleration so Injen is better then air box by far plus with the Injens aluminum tubing helps keep the air cooler then the stock plastic ****

 

$250 vs. $30 lol

 

Yea they have dynoes to prove injen makes power, but there is no dyno to prove that a injen intake makes more/less power than a airbox mod.

 

Not saying who is right or wrong but i heard than the plastic doesn't absorb as much heat as aluminum. But in the end what does it really matter?I don't think there would be a hugh difference

 

actually the metal is more prone to absorbing and heatsoaking from the engine than the plastic.

and there isnt any proof that injen is better than anything but the stock filter.


like i said. the performance of a CAI is in rerouting the air intake, and the performance filter.

there is no re-routing, and an airbox mod can use the exact same filter.

its just plain logic.

and ive experienced it first hand.

 

I tell you what i have a injen intake with stage 2 and 2.9 pully my buddy has a 60lbers and 2.7 pully and stock air box and i hit 18 psi and he hits 17 maxed out so you can not say stock is better then a injen intake and honesly i think plastic is worse then aluminum

 

firstoff the boost gauges in these cars are **** you cant trust them to make that kind of assessment.

have you both got identical exhaust setups too?

boost numbers are not an indication of whether injen is better than airbox on 2 different cars.

and you can think it all you want. metal will absorb heat more than plastic.



you tell me, exactly what part of a CAI is giving gains over the stock airbox mod.

keep in mind, i have a K&N Typhoon, if anything i should be defending it. but the truth is, they offer no performance benefit over a well done airbox mod whatsoever.

 

you can't compare 2 cars like that though. nobody said stock is better, the point is that the air box mod is just as effective.

 

Well i can honestly say we both have the same exhaust Magnaflow cat backs and same boost gauges and the first mod i ever did was the injen intake and yeah there was a big noticable improvement when i put in on and took off the stock one i guess its just your k&n typhoon intake that is not doing you no justice cause it is not helping you mine gave me better accelration and faster boost

 

I did the airbox mod as well because I did not want to spend 200-250 bucks on an intake. The sound was much better and it did feel like I gained a little bit from it. I put in a dryflow filter. I recently fell through the trap though and got a k&n typhoon on ebay. Reason being, guy was selling the kit brand new, minus the filter. I got it for 100 bucks shipped. So basically I got a full k&n intake with my dryflow filter for 140ish bucks. That is why I got it. Would I buy the whole intake if I had to start from scratch, no. I got a deal, so I went for it. I can let anyone know my thoughts of the airbox mod vs a k&n if they like. Should be on next week.
