If you had earplugs in, and we did a blind A/B test of stock versus your intake, you'd be incapable of reliably picking which was which. I promise.

For NY in general you can check:
Note that a dyno isn't really a great way to test an intake... because it's a device designed to operate when the car is moving, with the hood closed... and when you dyno it the hood is open (totally changes airflow) and the car is stationary (which also impacts temps and airflow). But even then, dynoed properly, you won't see more than a 1-2% hp gain from any intake. Anyone who claims more is lying to sell you their intake...and you can usually tell they're doing so- either because they show you 'stock' dyno that's way lower than every other stock dyno ever done by objective people...or because you can see an obvious mistake in how they did the test (ie there's an obvious shift spike in the graph, they did it in the wrong gear, etc)

I will reinstall it 2morrow and check everything again, even though I did it twice before and checked everything a few times before starting the car.

I should DINO it just for the heck of it.
u know any place in Bk by any chance?

|Knightshade||yeah, that's the cam gear rattle... free fix under powertrain warranty|

I started to hear a rattle on cold starts for 08 IS 350.
Is there a SB # for the fix.
Dealers usually try not to tell people about this until the warranty expires.

|bartkat||Check for leaks after the MAF. This would give an incorrect reading to the ECU and make the engine sluggish.|

Any power gains are entirely in your imagination- no intake adds enough power to make a noticeable difference in anything but sound on the 2IS. (quite a lot of folks mistake louder for faster though)
Ditto the throttle response if the intake is installed properly (which would be the first thing I'd check- to insure there's not some small leak somewhere in the intake path from something not quite tight enough).
The stock intake already provides more air than the engine is capable of using... it's not like an after-market one now magically provides "extra" air the car doesn't know how to deal with... (that's what the MAFS is for after all).... and thus an aftermarket exhaust, while it'll also add a small few hp, isn't "necessary" for anything else to work properly.

i'm new here and I got 2007 is350.
I had it for a little while now, but only recently finally bought an intake.
i read all over and decided Injen would be good, so i got it.
now the sound is awesome (loving it), hp and torque increase is definitely there, but theres a problem... i lost throttle response....not all the time, but sometimes when i step on the gas, seems like trany doesnt downshift and it seems like the throttle is behind.
someone told me that coming-out air is restricting that, and that I got to get an aftermarket exhaust, but i feel much more comfortable with stock one, at least for now.
did anyone ever heard of that problem and would know what to do?

|bartkat||That's the direct injection system. Usually hear it at idle. Yes, I believe it's a high pressure fuel system kinda like for a diesel engine. It's a normal sound.|

2008 is 350
Hello everyone I'm a newbie to the site and just purchased a 2008 IS 350. I love the car and reading this site has provided me with a lot of infomation.
I was wondering if anyone has encountered a problem with a constent tapping noise from the engine. It doesn't matter whether it hot or cold. When I accelerate I hear the tapping fairly loud.
When I brought it to the dealer, they tell me its normal due to the gas pressure in this type of engine.
Can anyone comment.

Is there an updated link containing all TSIBs and recalls for the ISX50?
The link in the first post of this thread is pointing to some domain hosting service.
