Description

The GM 3.0L Duramax utilizes an air-to-liquid intercooler to keep its intake air cool. However, the stock intercooler's performance is largely dependent on the efficiency of the front-mounted coolant heat exchanger. This heat exchanger absorbs heat from the intercooler coolant and dissipates it to the ambient air.

If the heat exchanger becomes heat saturated, it will greatly impact the efficiency of the intercooler, and affect engine performance. Heat saturation can result from prolonged high-load operations such as towing, or extreme ambient temperatures.

PPE overcomes the heat saturation issue with our High-Efficiency Intercooler Coolant Heat Exchanger. It features a 20 percent larger core and more rows of fins compared to the stock unit, adding about one full quart of coolant to the system for improved efficiency and heat stamina. The fully brazed, 18.5 fins-per-inch core and all-aluminum end tanks further boost its heat dissipation effectiveness.

We have also optimized the two-row coolant tube layout for better coolant flow distribution. The pressure drop across the PPE heat exchanger is 15 percent lower than the stock unit, resulting in a higher coolant flow rate and carrying away even more heat from the intake air.

The installation of the PPE Heat Exchanger is a breeze - no grille removal required. The stock mounting brackets are retained for a seamless fitment. This unit alone will enhance the performance of the stock air-to-liquid intercooler.

However, when paired with the PPE Air-to-Water Intercooler Kit, the combination delivers unmatched cooling performance, increasing charge air density, and transforming your 3.0L Duramax into a powerhouse.

Features
  • Core size increased by 20 percent over stock
  • Heavy-duty, all-aluminum end tanks for durability and improved cooling
  • Optimized core design for enhanced coolant flow distribution
  • Ultra-high efficiency, 18.5 FPI external fins
  • Bolt-on fit, compatible with stock mounting brackets
  • 3 Year Limited Warranty

Love it, nice for tough chewers, split in half during play
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
LOVE THIS PRODUCT, would’ve gotten 5 stars but i threw it for my dog and it split in half on contact with the floor. It had lasted us well over 5 months, it’s not his favorite toy but he’ll pick it sometimes, i wouldn’t say it’s unsafe in half just don’t give the smaller parts!

these incredible aggressive chew toys – they've seriously been a game-changer for my pups! I know it's a bit late, but better late than never, right? I've got a couple of power chewers at home, a Rottweiler and a Labrador, and anyone with big dogs knows the struggle of finding toys that actually last. These bad boys have been in constant rotation for over a year now, and I'm genuinely impressed by their resilience. They're incredibly tough! Funnily enough, we originally had three, but now we're down to just one. The others aren't broken, though – I'm pretty sure my dogs just loved them so much they've hidden them away in some secret stash, as they tend to do with their favorite treasures! Beyond just being durable, these toys have been a massive help with their training. They’re fantastic for redirecting all that enthusiastic chewing away from my furniture and shoes, which, let's be honest, is a huge win for any pet parent! Considering how long they've held up to some serious chomping, the price point is absolutely spot on. You definitely get great value for your money.watch your toe they are heavy. If you've got a dog that's a champion chewer, you absolutely need to try these out. They're a lifesaver!
