Pusher 3.5" MEGA Intake System with Cross-Air 2003-2007 Dodge CumminsThe Pusher 3. 5" Mega Intake System with Cross Air replaces all of your 3 factory post intercooler plumbing and intake manifold with 3. 5 mandrel bent tubing, heavy duty 5 ply silicone couplers and stainless T bolt clamps. This system provides the most airflow possible to the factory Cummins head, resulting in a significant drop in EGT's through better equalized airflow to all cylinders. The Pusher Mega Intake System with Cross Air increases fuel

The Pusher 3.5" Mega Intake System with Cross-Air replaces all of your 3” factory post intercooler plumbing and intake manifold with 3.5” mandrel bent tubing, heavy duty 5-ply silicone couplers and stainless T-bolt clamps. This system provides the most airflow possible to the factory Cummins head, resulting in a significant drop in EGT's through better equalized airflow to all cylinders.

The Pusher Mega Intake System with Cross-Air increases fuel mileage, throttle response and turbo spool. The Cross-Air taps into an existing port at the front and rear of the cylinder head that are normally sealed off with a freeze plug style fittings from the factory. By splitting off the driver-side charge tube and creating two additional parallel paths to those ports, cylinders 1, 5, and 6 receive significantly better air supply, greatly helping balance the engine temperatures and load at each cylinder.  

This entire package is fully TIG-welded, utilizing mandrel bent tubing, a laser cut 1/2" flange, and 1/4" dipstick mount. The intake manifold is standard equipped with four 1/8 inch NPT ports on the back for methanol/water injection, a boost gauge, etc.  

This is a complete kit that includes instructions, machined cylinder head adapters, heavy duty 5-ply silicone couplers, stainless T-bolt clamps, an OEM gasket and hardware, plus 1/8 inch port plugs for a quality install. Additional options include various powder coat colors, and extra ports. Custom colors available, please contact us for a quote.  

APPS Compatibility: This kit is not compatible with the APPS mounted in the stock location on 2003-2005 trucks. You must relocate or purchase the Pusher APPS relocation bracket to use the Cross-Air on trucks equipped with a APPS.    

Intercooler Compatibility: This product was designed to work with the factory intercoolers, and aftermarket intercoolers that mimic the factory inlet / outlet locations. If you have an aftermarket intercooler please call for the current compatibility list.

Nice for the price
Size: Medium, Color: B004
I really like the LALESTE Women’s Boyshort Underwear overall! They’re super comfortable, soft, and have great full coverage—perfect for everyday wear. The material feels stretchy and smooth, and they stay in place without digging in or riding up. Definitely a solid option if you like a more covered, secure fit. My only downside is that they are a bit too high-rise for my personal preference. They come up higher than I expected, so if you prefer a lower-rise fit, just keep that in mind. Other than that, the quality and comfort are great, and I still find myself reaching for them often!

Soft but easily rolls down
Size: X-Large, Color: B004
Comfortable and soft but it kept sliding down, I have a longer torso so that could be why, but I couldn’t get it to stay up, it would constantly roll into my C-section scar
