Im new to the Porsche world and was wondering which CAI is the better performiing kit. K&N or FABSPEED?I see there is a big price difference.That aside which one works best and is easiest to install?Also looking for any other small mods to consider for my weekend cruiser?Thanks!

 

Neither. Leave the Porsche intake as is as there is nothing better unless you are looking for more noise-IMHO

 

U don't see or feel any improvement in power?im just looking for I bit more power and a bit more aggressive sound can't hurt. Any other mild mods u suggest? If that's your Gt3, it's awesome!

 

I love my K&N!

 

There is no gain in power other than in your mind and that is based on the increased sound levels. That you will get especially under load. Not much you can do to increase power on the naturally aspirated 996 (other than increasing bore size or forced induction), which cost a lot.

I would recommend a "good" set of 200 cell Cats though. I like Cargrahic or AWE, but there are probable others. However, they are not that cheep. But, that will help--IMHO

 

I was thinking CAI and muffler delete?

 

Any changes you make to the exhaust will change the performance characteristic (power curve) of your vehicle (i.e., you may gain at the high RPM range but you will "lose" at the lower range). Meaning you will loss low-end torque.... Deleting your mufflers will make a lot of noise thats for sure. But more torque and power---no. And if it does, it is at a high RPM where you normally dont drive. And it will not be much-IMHO

 

None

 

I'm surprised to see that u guys are saying that none of them are good! Which mods are recommended?

 

K&N most WHP
Evo safest system

The two make between 5-10 whp, per dyno results.

The GT3 RS 4.0 uses two conical intakes (CAI) stock. Even Porsche see's the light that's been shining for over 15 years with good intake brands.

 

Please post the validated dyno results on this data. I am interested...

 

K&N include a dyno graph with the kit that boasts 21hp gain and Fabspeed have dyno graphs on their site for their CAI if I'm not mistaken.

 

Yep... At 6000 RPMs maybe but I doubt "21" HP no matter what their graph says.. Gee if it was that easy Porsche would have done it... However, I am sure that they probably yield some power increases on higher output race motors (with other modifications) but on an average street car it is probably not much of an improvement, other than sound---IMHO

 

NO, I don't play that game. You do searches, I really don't care what you think.

I've experienced it for almost 2 decades now at dyno events I've hosted and have participated in. I've seen identical cars with as little as 5whp advantage, due to intakes only, beat others on track and street. However, I can agree some intakes are worse/better than others but that's what dyno results are for.

Call Porsche and ask why they have conical intakes on the GT3 RS 4.0.. Tell them it's a waste and only made for noise and looks.

 

All bolt on's including, plenums, ecu upgrades, exhaust, cats, downpipes, etc... have ridiculous dyno claims and if you add all of those up you would have damn near 100hp if you purchased them all. But anyway, from "my" experience I've seen no more than 10whp from an intake alone but on average I see/seen 5whp to 7whp. On the road 5whp is significant.
