So, my OEM air cleaner needs to be replaced, and I figure it's the perfect excuse to spend the money and upgrade to a Z-Tube. The concern I'm having is that I just spent the past hour or more reading reviews making claims that neither the Z-Tube or Cold Air Intake yield any (significant) horsepower gains. www.conceptZperformance.com has an inexpensive JWT Pop Charger with Stillen Z-Tube combo with the claim of a 12hp gain. I'm hoping for improved throttle body response and a bit more aggressive performance. I understand a 5/16 plenum spacer is also a wise investment. Before I spend the money, I want some feedback or advice from people who've upgraded their intake systems.

Thanks.

 

the plenum spacer is money better well spent...get a ztube and a drop in KN filter...if you want a CAI I have a brand new short ram Fujita ill sell for $125 shipped...its never been taken out of the box

 

Intake isn't going to help much. Really it's more of a sound thing. There hp numbers are lies.
Only time an intake will do anything is on real old cars that weren't designed well and don't get enough air through stock system. All newer cars have suffecient intake for there motor

 

Read around, intake is for sound and bling. Switching to anything but stock has most often been showen to just cause you to lose power. Save your money for other mods unless you are looking for one of the first two mentioned things.

 

There are plenty of dyno tests that should improvements in horsepower. HOWEVER, when you read them carefully you will see that the gain is only for specific power ranges (as are most performance mods). A Z-tube/filter upgrade combo will yield a SMALL gain in the mid-range power so you will not get better throttle response nor top-end. The only place you will actually SEE a difference is on a dyno and the only place you will FEEL a difference is in your butt as the engine will have s more aggressive sound/rumble.

 

You wanna cite your sources??

Pretty much every intake loses you both max and average hp. Sure you can nitpick through the individual dynos and say maybe at one rpm an intake may gain a few hp, but overall avg and max is still a loss. Intakes have been and always will be worthless performance wise to our cars.

 

Those sources say the same thing, very narrow gains in specific areas. You have to look at the dyno tests very carefully to see through the BS

 

What are you trying to say? Intakes for our car are widely known to MAYBE give narrow gains in some spots but lose in many other spots. Not to mention how almost every aftermarket intake suffers much more from heat soak which as situation all of our cars will face.

Are you trying to say intakes actually give anything near significant gains?? If so, I don't know where in the world you got that idea from...

 

Ever feel like you've answered this question before? Intakes by themselves don't add much whp....fact! However, once you've completed your breather mods which include spacer/exhaust/hfcs the z-tube and intake like Stillens contributes to whp when getting a tune! FYI: Stillen's Z-Tube/CAI is the only intake that won't cause you to lose whp when it's hot!

Love my Stillen Z tube and CAI. Box is sealed off and reusable cone filter with venturi ring.

 

Ahhhh grasshopper not quite true. The R2C seals against the hood and leaves just the front open to draw cooler air in from the bumper. Troof.............

Seriously though I dumped a pop charger after having it on for 3 weeks in the brutal Texas summer and replaced it with an R2C and the difference was night and day.

 

Is the R2C intake pipe plastic or metal? I thought it was metal and figured there'd be heatsoak but if plastic, yeah that would be nice

 

A snail is the best intake.

 

itb ftw lol

 

It's plastic.
