Need source for EGR block off for LS1

**Jglisson** · 10-07-2007, 05:46 AM

I used to seem them on Ebay for around $25, but I don't see any now. I need an EGR block-off kit for a 1999 Trans Am with LS1. Thanks....

you can also just use an expandable freezeout plug for the intake in addition to those exhaust block off's

Orion,

Thanks so much for the info. I also checked out Speed Inc. The best I can understand I need the following for the complete EGR delete:

Speed Inc
Emissions Block-off Plates
CNC Machined, perfect fit, elimate your EGR on 98-00 cars and your A.I.R. injection tubes on 98-02 cars. EGR Plug: Plugs the hole in your F-body LS1 intake when eliminating the EGR. Simply "taps" into place.

Off-Road Use Only

item no description price buy
SS198 LS1 EGR Header Block-off Plate $8.00 buy
SS298 LS1 AIR Block-off Plates $8.00 buy
SS398 LS1 EGR/AIR Block-off Set $14.00 buy
SS498 LS1 EGR Manifold Plug $2.00 buy

Is this correct?

Are you just getting rid of the EGR or the AIR system as well? If just the EGR you need only the SS198 LS1 EGR Header Block-off Plate and the $2 plug. If you are getting rid of both you need the SS398 LS1 EGR/AIR Block-off Set and the plug.
