you can also just buy the ztube and attach it too the original filter.

could be wrong, but I thought they were similar with the exeption of JWT's concave style filter on the front part.

Thanks for all of the help guys, I actually went with the K&N cold air intake. Can you go with a spacer and K&N cold air intake combo and if you can how much will it improve performance?

I honestly cant even hear my z-tube. That was only the first 2 days. I would recommend Stillen because it is fully enclosed from heat.

I have heard from a few locals that they felt they lost power with the jwt in the summer. One even said his car was sputtering.

Hmm I have JWT and I dont have any problems... I Love my Ztube and Pop charger Both Sound amazing together!

I live in Vegas Heat too so its def one of the hottest summers thats forsure!

Good info for later on.

not much of a difference between the two. just go for the one that you find cheaper imho. hope this helps brah

I concur with many of the above posters. I don't know much about cars either, but I went with the upgraded Stillen intake, the 5/16s isothermal spacer from MD, and I have a Z tube. It definitely added a lot more bark- but whether or not it added more "bite?" Hard to say because I don't have the figures from those days. I remember the first time I stomped on it after the install I was REALLY impressed by the authoritative growl... but was somewhat neutral about the actual performance gain.

It wasn't until I upgraded the back half (HFC and catback exhaust) and got a tuner and some time on the Dyno that the car really came alive.

Do you mean a drop in K&N filter? Sorry, just a bit confused.

Yes he did.

It will increase the performance as much as the spacer does but then you have to subtract the loss of power due to the cai. Do more searching and you will see intakes on these cars are for nothing more than sound and bling.

danke

it was super late for me. ha.
