...Resulting in more upper rpm range horsepower, sometimes at a sacrifice of low rpm torque.Originally posted by HIBBoyScott:
Yamaot, you don't NEED an exhaust to go w/ an intake, but the more free flow you get (to a certain point) the easier it is for the engine to breathe, resulting in more power.
350+ for the intake huh? Not bad I guess.Originally posted by mryuen:
...The rep from RM said it would run about $350. The exhaust will be rear section only, not cat back due to the resonator...
no you just replace the current intake - which is very small and narrow... and only about 1 ft wide.. the way this mod intake is placed, may in fact get in the way of installing a turbo or s/c - since as far as I can tell, the only place for one is immediately left of the engine and that's were he currently has a rather large intake pipe...Originally posted by IS300Purformance:
Again this might be a dumb question, but do you need a turbo kit or a s/c kit if you're gonna put an intake in?
Hey I've heard good things about K&N filters, will it give me a hp boost, and is it worth it?Originally posted by Jebzter:
For those who just want to change their filters...
K&N has just released their filter for the IS300!
You have to contact them directly and order them...

It makes a whole lot of difference when they change ECU settings to match your intake. (e.g. Dinan offeres a chip/air intake package that guarantees 15-20 hp on the 3-series...my friend has one...and it is AWESOME!!!!!)
it will not make your car very load...considering Lexus' sound insulation in the cabin is superior to most other cars.
My integra has a AEM cold air intake, and only makes the cool vacuum noise up high in the rpm range. Sounds more cool than bothersome really. The mustanks and crapmaros sound loud as hell because of that cheap flowmaster they put in and they're load to begin with. I don't see the Lexus having the problem.
