Default GS300 Injen Intake installation questions.

Hey guys, I been searching all day and can't find the manual for the intake I just bought from another CL member.

It is the Injen 01-05 GS intake.


What is that piece and where does it go? Is there something I need to look out for so I do not trigger the CEL?

Thanks and sorry if I missed another thread with all the answers.

It's to hold the intake down on the opposite side of where that black hose is.

Thanks for the reply,

Do you have a picture or something to use as an installation reference?

This is for the 98-99 GS300, but pretty similar

sorry, didnt see the thread earlier.

it doesnt thru any codes, so long as all 3 hoses are connected and the maf sensor is connected.

ive read on clublexus the reason it may not be throwing any codes is because injen sends u a small air filter. the filter it comes with is significantly smaller than regular filters u get with any other short ram.

as for hp gain, i doubt much if any because, from what i read, the ecu corrects for it. had i known this info earlier, i probably wouldnt have gotten the injen.
