Intakes... are they ALL just a scam?

christian370z

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?

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)

Pelican170

Correct, but im pretty sure the dyno that someone on here had for the post MAF tubes showed like a 10 - 12 hp gain after he had exhaust parts, so that makes them all very close in hp when said and done. Granted, i do feel 10 - 12 hp for those tubes seems high...

I have FI LTH and non resonated TDX. I dynoed without the intake then installed the G3 while the car was still on the dyno and did a few more pulls. The G3 gained another 10hp over the previous pulls.

Good info, and pretty much inline w/what I'd have guessed, So the G3's are worth around 10whp when in conjunction w/other mods. Wonder how the drop ins w/post maf tubes would stack up under the same conditons, I'd bet they'd be worth around 6whp or so.

I guess the best way would be to look at people's sigs and see what kind of numbers with each that people are getting with similar mods. It's also going to be what works best for each person... if you have the drop in's and PMT's and have 5 or 10 less hp, is it worth the extra 250.00 or more once you sell your drop ins and pick up a set of G3's? To some it is and some it's not... with an NA car I have learned that every hp is hard to gain so take advantage of what you can get... but you'd be better off to just get it right off the bat instead of wasting money buying something else first.

It's hard to compare though because people use different dynos which would be different brands (dynojet, dyno dynamics, mustang dyno etc.), as well as have different internal calibrations.

Check out this blog and the dyno results. All mods are posted for each car and it is on the same dyno which will help you compare:
