Which intake will give me the most whp gains? on an is350

1. Lms

2. K&N

3. FUJITA

4. Joez with hks drop in filter..

5.Injen

6.aFe

Dude, You Forgot Injen. I Just Installed Mine On Friday. I Feel The Extra Power On Mid Rpm's In My Is 250.

do a search.

#4 MAY give you some gains.

#1-3 add noise, but you'll likely lose whp. yes, LOSE whp

JoeZ is the best for this car!

Yup, I'm loving the JoeZ intake upgrade. Simple in design but surprising an effective hp gainer (5-6rwhp).

a filter on a stick or a drop in does absolutely nothing you will feel. You'll definetly hear it. Without a hand full of other supporting mods that don't exist yet for this car, changes to the intake are nothing more than an audible placebo...

i concur. If whp is the goal, then the time and expense of changing an intake is not worth it. IMHO.

i see the header for the is250 when we getting them for the is350???

Go LMS cold air w/ Apexi Neo for best gain!

i thought the lms gave no gains.. according to other forums

None of them give a SOTP gain. They're all a little or a lot louder.

just installed the injen..its good why dont you have it in your 4?!

several people have reported gains..
Javy reported like a 7hp max increase with his K&N intake

So where to get JoeZ?

I have Injen SR intake, HKS exhaust (not the high power one) and have dyno numbers showing a little more then 12rwhp gain......(this will probably start a hole thing again so to save the agony check out my previous post and the dyno sheets are there)
