Need more air? Your stock intake manifold can be restrictive, making bottlenecks in your air intake system which robs you of performance! Grab Wehrli's Y-Bridge kit that can increase airflow by up to 50% so your engine gets to breathe free.

NOTE: While some colors are kept in stock, other colors will take an extra 10-15 business day delay in powder coating.

Wehrli's Y-Bridge Kit comes with their high flow 3” kit to increase throttle response and turbo spool up by creating a full 3" intake tract from the intercooler outlet to the engine. Eliminates the angled OEM intercooler boots that are prone for failure. Includes FPRV Block off kit to allow proper clearance to larger diameter Y-bridge.

TURBOCHARGER NOTE:
NOT RECOMMENDED FOR USE WITH S300 OR S400 STYLE TURBOCHARGERS. If you are planning to run a turbo other than an OEM / IHI style upgraded drop in on your setup, please check out our S300 Single Turbo Kit WCF100478 and our S400 Single Turbo Kit WCF100489 or call us for help placing your order.

Fitment Note:
2001 models have the MAP sensor installed on the intake runner rather than the bridge from the factory. Due to the increased size of our bridge over stock, in order to install this kit you will need to relocate the MAP sensor to the port on the new bridge assembly and then drill and tap the runner to install a pipe plug (not included) in the original MAP port location (or source a new intake runner from a later model 02-04 LB7 truck).

shirt is thin, sizing is useless
The shirt is thin but okay. The sizing is useless. I purchased a large and a medium. Each is marked with the size (L and M), but the two shirts are exactly the same size. Laid flat together or held up by the shoulders together, these two shirts are EXACTLY the same.

Fun Christmas Sweatshirt
Color: 02 Green, Size: Large
I really like this sweatshirt. It was listed as men's so I ordered the large. The sleeves are pretty long, which I really like. Otherwise it fits slightly baggy, but I typically wear a women's large so I ordered the large hoping for a little bit oversized. The material is typical for what a normal sweatshirt is, but is a little more lightweight, which I like. It being a touch thinner allows for easier layering and not peeling it off halfway through the day. The graphic is nice, the colors are bold and crisp. I love Christmas and love having tons of different themed clothing to wear, so I'm super excited to add this to my stash.

Great
This Holiday sweatshirt is great, It's made great with soft materials. It fits perfectly not tight and not bulky. It's warm and can be worn over a t-shirt or a long sleeve shirt when it's cold outside. It doesn't twist or ride up. The design is well made and looks great. The colors are bright and look nice. It's great for the holidays but after they're over I'm going to keep wearing this because I like it. It's a great price because with proper care this sweatshirt will last for a long long time.
