APR is pleased to present Boost Leak Testing Systems for various engine configurations.

Boost leaks are a common cause for running issues and power loss on turbocharged vehicles. Leaks can come from scenarios as simple as a tiny hole in an intercooler or charge piping, a leaky connection, damaged DV or PCV and/or any number of other locations making troubleshooting very difficult. Furthermore, locating a leak is made more difficult due to the necessity to pressurizing the system, which typically only occurs while physically operating the vehicle.

The APR Boost Leak Testing Systems allows for both visual and auditory inspection on a stationary vehicle. The kit allows for supplying and regulating a continuous supply of compressed air, typically via an air compressor, through the system.

The process is simple:

- Connect the adapter to the application specific connection location (usually at the turbocharger).
- Connect the pressure regulator hose to the adapter's bung.
- Ensure the pressure regulator is turned all the way down and then connect a continuous air supply to the regulator.
- Pressurize the system to normal operating pressure.
- Listen for leaks and spray soapy water on connections and look for bubbles to indicate a leak.

Once the leak is found, simply take the necessary steps to stop the leak and go on enjoying more power and a better driving experience!

This topper has definitely provided me with better, more comfortable sleep.
Color: Green, Size: Twin
I recently tried a twin mattress topper made from bamboo-derived viscose, and I'm quite impressed. The topper is thick, waterproof, and offers excellent comfort, especially for those who struggle with back pain or sleep hot. The bamboo and polyester blend gives it a soft, cooling surface that's perfect for a restful night's sleep without the sweaty feeling often associated with memory foam. What I really appreciate is its dual function. It's breathable, allowing for good air flow, and fully waterproof, which helps keep the mattress underneath safe from spills. This is especially useful if you have kids or pets. The topper's thickness is just right—it provides great support without feeling too soft or too firm. It cradles pressure points well, offering relief to my hips, back, and shoulders. The fluffy filling holds up well over time, maintaining its softness and support. It fits securely on mattresses, thanks to a deep pocket skirt that prevents any sliding or bunching. This topper has definitely provided me with better, more comfortable sleep.

Soft and comfy
Color: Green, Size: Twin, Color: Green, Size: Twin
This mattress pad is much thicker and fluffier than the one I had before. With I took it out of the package, it was vacuum sealed with a note saying to leave it out in the sun for 48-72 hours or fluff it up with a hair dryer. I put it in the dryer on medium heat, which worked nicely. The pockets are really deep on this mattress pad and it fits snug. You don’t really see the shape with a sheet on top. It feels comfortable laying on top of it. It doesn’t flatten much when I’m laying down, but I imagine over time it will lose fluffiness. Overall it’s comfortable and breathable.

Good for already soft mattresses, 1in thickness.
Color: Dark Grey, Size: Queen
If your mattress is already soft, it will help. It's less than 1in thick after tumbling for 40 minutes. It did fit my queen bed and felt somewhat soft when laying down but it didn't help much as far as comfort. Quality wise it looks good, not cheap and while my sleep quality wasn't improved, it might help someone with a better mattress than mine.

Must have for mattress comfort and protection
Color: Green, Size: Twin, Color: Green, Size: Twin
I ordered the BDEUS Twin mattress topper for a temporary mattress. The topper definitely improves comfort and regulates temperature much better than just the mattress and sheets. The cover fits deep mattress easily fitting over my 13” mattress and could easily fit a much deeper bed. The padding is thick enough to provide some additional support. This model also has a thin sheet of waterproof material to help protect your mattress against spills or liquid damage. This layer is cover by the pillow top and does not seem to make much if any noticeable noise. Overall this is a high quality cover and mattress protector in one. At <$45 at the time of this review it provides an incredible value.
