thx
Wow how did you get them to refinish your wheels under warrenty? I've seen some factory wheels from up there that look pretty grungy because of the salt, but I had no ideas that was covered under warranty.

They lie. No intake adds even half that.

No, you really, really can't. You're talking about, maximum for any intake, a hp difference of 1-2%. You can't "feel" that. You hear more noise and think it's faster. It's a common thing, but that's all it is.

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.

In Brooklyn?

For NY in general you can check:

http://www.dynojet.com/dyno_centers/....aspx?state=NY



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)

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.

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

Jim Matera Hey Brian

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.

Thanks

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?
thx.

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.

Thanks

I just had this done to my car. Didn't notice any difference, but I was on empty and they fill up your tank when they are done!

diabl0 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.

Thanks

I just had this same TSIB performed on my 06 IS350. Its alot quieter now....
