I'm about to embark on my first engine mod. I've found a few threads on the best intake for the IS350, but nothing specifically for the IS250/AWD. Does it really increase the hp...if so, can you tell? Also does it effect the warranty?

Which intake system is best for this car?

Thanks guys!

 

most anything that helps with an IS350 will help with an IS250.. no you wont notice anything, except sound with most intakes.. you can get a Joez for about 100 bucks and gain about 5 hp.. your warranty will be ok

 

JoeZ all the way, adds an agressive look to your engine bay and is by far the best value. ( +adds some kick )
