Intakes... are they ALL just a scam?

Methodical4u

what about the dry drop ins ? I forgot the name of them.

K&N?

as people said the stock intake is pretty good. The Stillens would be better. can you properly test the gains on a dyno, its hard.

Find a dyno that is in doors in a temp controlled facility and with a wind tunnel and the testing will show that the stillens are probably the best (just be design)

The OEM is probably on par with the AEM / Injen except for the rougher tubing / more restrictive filter.

The issue mostly comes up with gains/$

But, i can tell you that when i removed my stillen Gen III's theres definitely a flat spot in the power at the high end.

AFE Dry Flow Filters. I have them in with Post MAF Tubes... I like the setup and not having to oil the filter is a big plus in my book...

We're mixing up price with performance. When it comes to performance gains Stillen and Injen are the best, they place the filters far away or out of the way of hot air thus creating more power.

The bang for the buck intake has been the MAF tubes and drop in filters.

Personally I went with Injen but I got them slightly used from a forum member at a very good deal, haven't had a chance to dyno since the install.

If you really want to wake up the Z and you plan on staying NA throw down for some gears 4.08's will really wake you up.

Not exactly as clear cut as you make it seem. There are far too many variables to determine how much hp's translate to weight. Its more relevant in race type environment like a drag strip.

The thing to consider about breather mod's is that they do add up. It's a give and take. There's only so much you can do with intakes in general. $500 or so for the Gen 3's is a lot, but so are most CBE. Technically I can see why they would charge that much since essentially you are buying two intakes.

The drop-in's will likely net you 6-10 hp @ the wheels which translates to a few more at the flywheel. Not bad for under $200 IMO.

What are the downsides or disadvantages to getting 4.08 gears, especially considering a Z that is DD and driven mostly on the highway? I've asked this question around in a couple of different threads but never really got an answer. I'm interested in getting them, but not if they severely affect the DD capability of my Z.

you're engine will run at higher rpms with the 4.08's. This will lead to decreased gas mileage, and more wear on tear on the engine. (it takes more energy to drive at 3400 rpms than 2800 rpms)

your first gear will also be super short, and all gears after that you will move through quicker.

ive been back and forth between getting them and not.

also, you have a 7at so you will also need a manuel rear end to run 4.08's.
It will run you close to $4k including labor to have this done just so you know.

Well that makes my decision easy!

How much would it be not including labor? I may have some friends who are very skilled with working on cars and maybe able to help me do it for a lot less.

i was quoted at like 3500 but that included an LSD i think, so 2500 ish


apparently its not a very easy job. especially for the auto guys.

That sucks. Eliminates that mod as a possibility for me.

The gains are already proven: Stillen still makes the most peak power, second Injen and third are the K&N drop ins and post MAF tubes. However, to get the most out of the Stillen intakes in particular, I still believe that a tune is necessary in order to tune the A/F ratio for safe and optimal power as the different diameter of the G3 intake pipes will cause the MAF to see a higher total volume of air flow.

There are numerous threads on this whole debate already, I think the title of the thread only serves to stir a well documented pot.

I thought ive heard that these gains are like 14 - 18 or whatever but thats on stock cars. Once you put exhaust pieces on they drop to close to what the Post MAF tubes create with exhaust pieces on. Thats why people go for them. Has anyone with exhaust pieces on their cars dyno'd before and after with any intakes?

Cmike2780

I think you can gain some of it back with a proper tune and net a larger gain overall with the Gen 3's.

so.. why would the stillens gain be lower when you have an exhaust and not the post maf tubes?

truthfully the gains by both would be lower (if the post maf even gives any gains)
