Cable Bracket for 65mm LX5 TB

(Pics coming soon) Our revised cable bracket bolts to the front of the throttle body, making it compatible with both the 3100/3400 upper and 3500 LX9 upper intake.  

EGR Block Off Plate

1/8" Aluminum plate to block off the EGR port on the intake manifold.  For off road use only.  M22x1.75 plug for the exhaust manifold is not available at this time.  

3400 Header Flanges

3/8" Thick Mild Steel Header Flanges Designed for the aluminum head 2.8, 3.1, 3100, 3400, and 3500 LX9 engines.  1 5/8" round ports with no overlap into the ports with the primary tubes installed.  Easy access to the spark plugs without removing the headers.

Ported 3500 LX9 Manifold Set

The best flowing 3500 manifold set we have to offer.  We have found this set to free up 3 cfm at the intake valve (at .500" lift) compared to gasket matching.  Gasket matching is better than stock, no doubt, but it is leaving performance on the table.   We do not use a core system due to dish…

LX5 65mm Throttle Body Adapter

We have designed an adapter to use the 65mm TB found on the Oldsmobile 3.5 DOHC. Bolting it to the manifold (3100, 3400 or 3500, both bolt patterns and sets of bolts are included) is no problem, but attaching the throttle cable bracket will be a DIY project.  You will need both gaskets for the 3400…

Ported 3500 Upper Intake (2004-2006)

We offer 2 stages of porting for the 3500 upper intake, which depends on the application.  Stage 1 uses the 3400 plenum gasket as a template for use with either a 3400 or 3500 lower intake that is stock, or also Stage 1 ported.  Stage 2 uses the larger 3500 plenum gasket as a template and can only…
