Getting ready to install a JCW Intake.

Should I "gut it"; remove flat before install, or install it with all of the hoses and flap as is from the factory?

 

My vote is to remove the flap and various flap control parts (hoses, canister, vacuum diaphragm, linkage, and wires) plus attached a plate over the resulting hole. I glued a thin plastic square over the hole. But there will be a little more intake noise with the flap removed. I like the extra noise.

 

Just my .02 here. If you want to gut the JCW out, why not just buy an Alta? The flap & the fact the JCW is quiet until the flap opens is what the JCW is all about.

 

I got a good deal on the JCW, cheaper than the Alta.

 

Great deal, why not install it & see if you like it before you gut it? Your intake, your choice.

 

My take is that if you feel like you might not want the flap, just take it out. It's a very quiet, subdued intake (mine's back on after I screwed up my Dinan), and the added noise without the flap is nice to hear.

Running mine with the flap in and the lower plug removed, perfect!

 

One mans nice sound to hear is another's bothersome noise. Different tastes, noise doesn't = power.

 

That's how I run mine. Perfect for me too.

 

I may have to give that a shot. I've got the flap removed, and I could actually do with a little less intake noise. Maybe if the car felt stronger...

Right now I feel like it's making more noise than power.

 

Put a K&N RU3130 filter in mine too and it will make plenty of noise if you want it to, but doesn't scream at you when your on the highway..

 

Also matters whether or not you have a throttle that whistles like Andy Griffith. I went from Dinan to JCW with the flap and plug to hide the whistle, but still get the SC while at higher revs. I like.

Like some others, I recommend you start with the JCW "stock" and then modify if it's not to your liking...
