Hi everyone! I wanna ask about the K&N air intake and the JOEZ pipe with HKS filter for my is250. Which one is better? Which one gain more HP?

The Joe Z is about 5 hp.

Everything else is more money for the same, or lower, power gains.

(and none of the above is enough to "feel" but at $125 for 5 hp the Joe Z remains the best hp per dollar mod available for the 2IS other than maybe nitrous.)

what about the f-sport intake? I think I read that it gives 5hp as well.

joe z will give you gains in power, but no loud intake. doesn't matter what filter you use. paper filtrates the best and there's no difference in power between filters. i think caymandive actually lost power with a blitz filter.

k&n will probably result in a loss of power but will be loud if you're only into noise.


if you go with a short ram intake. i say go with one that uses a dry element and not oiled.

The F-sport is basically a copy of the Joe Z, with a replacement lower airbox that has a second hole drilled in it to make noise above 3000 rpms, but as far as anyone can tell, provides no functional benefit other than noise over the Joe Z.

(some Joe Z owners have gotten the same result noise-wise by just drilling a similar hole in the stock lower airbox)

Everyone here is a biased Joe z nutt swinger, they don't have proof of what they know but dynos from Joe z itself, no independent tests

^ are you saying that people are stating that joez intake gives 5hp according to Joez dynos?

Kurtz

That appears to be what he's saying but he has no idea what he's talking about...

But folks have done independent dynos of the Joe Z, which he'd know if he'd taken the time he's been using to spout off in ignorance and just run a quick search.

To cite one example (from a well known member)

WoW… LoL

ALL of my R&D Dyno's on the IS250 & IS350 from 2006 were indeed Independently Dyno Tested & Proven by SP Engineering here in Southern California...

And that's a fact "jaxxx"..

Best Regards,
