Ultra Series forged pistons from JE are the industry?s strongest, most fully featured pistons available off the shelf. Offered for a wide range of import and sport compact applications from 2JZ to 4G63 and Audi to BMW, Ultra Series pistons feature JE?s proprietary Aligned Grain Flow forging technology providing next-level tensile strength ideal for the extreme cylinder pressures of power adder engine builds. Equipped with custom level features including thermal barrier crown coating, skirt coating, gas ports, and more, Ultra Series are the ideal pistons for your high-boost build. As with all JE Pistons products, Ultra Series pistons are made 100% in the USA.

  • Aligned Grain Flow Technology: Exclusively available on JE Ultra Series, this proprietary, in-house forging process maximizes tensile strength to withstand the stresses of high-performance engine environments
  • Thermal Barrier Crown Coating: This ceramic-based coating reflects heat into the combustion chamber, therefore reducing piston crown temperatures and improving exhaust gas scavenging
  • High-Strength Wrist Pins: Premium thick-wall wrist pins are manufactured by Trend Performance in the USA and are designed for the demands of high-performance/power-adder builds
  • Skirt Coating: Reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise, especially on cold start
  • Optimized Pin Oiling: Enhanced pin oiling features keep pin, pin bores, and small-end lubricated for reduced heat, friction, and wear
  • Lateral Gas Ports: Help maintain power-producing ring seal at the top compression ring, even in high RPM and high boost situations
  • Designed for Power: Every feature on Ultra Series Pistons are optimized to perform high-horsepower racing engines
  • Made 100% in the USA

Efficient long lasting. Great Value
Style: CF10735 Classic
These filters (my second one) has lasted me over two years with a little maintenance in between, (removing from time to time to vacuum and shake out the bigger debris.) They do a great job of keeping the cabin air really clean and fresh. 1) Over designed and built (Good thing) installed without effort. 2) Fit and finish is perfect for my 2016 Genesis G80 3) Carbon filter works well but after about six months it no longer absorbs orders, This is excepted especially when I have not swapped it out for over two years. 4) Great value and honestly I should be replacing these cabin filters out ever six months for efficiency and order control. Note: When I decided to replace it the filter held up structurally as the day I installed it. The charcoal beads where all intact as well.

Great Air Filter
Size: 9.6" x 11.1" x 2.2"
Some review’s will say “it’s an air filter, blah, blah, blah”. These reviews are written by the same people that think “water is water”. I’m not one of those people. I’ve noticed that the air smells better, cleaner. I’ve also noticed that the air blows a little stronger. It’s very easy to install, fits perfectly and it’s reusable so it saves you money over the long term and it reduces landfill waste.

THE cabin air filter to use!
Size: 9.6" x 11.1" x 2.2"
I replaced the OEM cabin air filter when I bought my truck, like I always do. 2019 & 2020 Ram 1500's suffer from an underperforming AC system in the summer due to a blend door in the dash not closing completely. Having any kind of restrictive cabin air filter only exacerbates the problem. I bought this filter on the recommendation of many owners who had done the same with great results. I was presently surprised at the increase in air flow coming out of the vents. I also like that in K7N fashion, it is washable and reusable, effectively making it a lifetime filter. Don't overthink it. Yes it costs more, but you will save $$ in the long run with this filter. I am sure this filter fits many other makes & models of vehicles and will improve the airflow of any vehicle it is installed in.

Easy to install and fits great
Size: 9.6" x 11.1" x 2.2"
Fits great and seems better quality than any paper filter. Nice rubber edge makes a good seal and the airflow is good. Used in a 2023 Ram 3500. Installation was easy. So far it appears to filter out all the dust and odors.
