PLEASE NOTE!
Built for 2006-2010 LBZ/LMM Duramax owners, this 3-inch Y-bridge and cold side pipe kit improves airflow, reduces boost drop, and replaces failure-prone factory plastic components.
LBZ/LMM 3" Y-Bridge Pipe Kit Overview
Upgrade your Duramax’s performance and reliability with the SPELAB 3-Inch Y-Bridge and Cold Side Intercooler Pipe Kit. Designed for 2006–2010 6.6L LBZ and LMM Duramax engines, this kit replaces the restrictive factory plastic components with high-flow mandrel-bent aluminum pipes and reinforced silicone boots. The addition of a free-flowing Y-Bridge enhances throttle response, reduces boost drop, and ensures consistent airflow under heavy loads or performance tuning.

They make the parts affordable thank the lord, got the website from my mechanic but he never tried them yet- I gave them a shot now I get it
Looks good and very good quality
Y bridge was fully powder coated causing install issue. Had to remove powder coat from mounting surface to some what fit better.
Price point is good. Had to remove the finish on the mating surface of the intake to get it to set right.
Initial fit up of the bridge in the valley was trash. They powder coat the flange where it bolts to the manifold, so you have to sand the flange to get it to fit.
I had review a 1 star by accident .
I am very happy with the product and its fitment
Looks great.!! 👍🏾😁😁

I have yet to put it too the test but the y bridge is installed and it went smoothly. Looks nice and well built!!!
The color was not what I was expecting and it was a little tighter fit then I would have liked but it all fit and sounds nice
Waiting on shop to finish the job so I don't how good it works
Worked great for modifying for lly runners, no leaks.
It fit well,and seems to be very high quality.
THE KIT FIT PERFECT. THE ONLY ISSUE WAS THAT THE ONE OF PIPE ENDS WAS SLIGHTLY BENT WHERE THE HOSE CONNECTED.CAUSED SOME LEAKAGE.HAD TO BRING IT TO THE LOCAL MUFFLER SHOP TO MAKE IT A PERFECT CIRCLE. MAYBE BETTER PACKAGING WOULD HELP FROM BANGING AROUND DURING SHIPPING.
Fitment could be better and could come with the pipe plug for the pipe tapped hole on the intercooler pipe. Other than that not bad. Would recommend using RTV and Y bridge O rings when installing on truck. Prevents future boost leak.
good communication
great service / fast
great problem solver
Thank you for your review and look forward to receiving pictures of your feedback on the installation!

I did new head gaskets as well, and a delete, this all woke up the lbz up and it runs amazing!

The price was very good, I had to drill the holes bigger so that I could get the bolts to line up with the tapped holes.

Thanks for the review!!!
I finally received the package containing the Y-Bridge pipe kit. It came to the wrong address thanks to FedEx. It took me 4 days to track it down and then I had to go pick it up. Then I had to drive 50 miles to a neighboring county to purchase the square gaskets for the Y-Bridge pipe itself. It definitely would have been more helpful if they came with the kit I ordered from your company. Overall, the Y-Bridge kit was just what my truck needed. The extra stress however was not what I needed.
Hello. I'm very sorry. Provided you with an unpleasant shopping experience. You can contact SPELAB's email to receive compensation gifts.
Bolt holes for the y bridge did not line up. Had to drill them out to aline. Also high flow elbow did not line up. Was a little off. Had to cut and re-weld. Clamps are vary cheep as well. But still saved me over $600 then buying a name brand one.
Hello. I have already provided feedback to the product development department regarding the issue you raised. I am very sorry for the unpleasant shopping experience you had.
Fit lbz great! Lmm seems the intercooler pipe hits Altinator stud hard
Thank you for your review!
How does the throttle body connect back to the cold side?
Thank you for your inquiry. I apologize, but the factory has stated that there is no installation method available. For further information, please contact us at: ( service@spelabautoparts.com).
