They look terrific in the car. It's a great way to keep an eye on the condition of things under the covers.

Perfect fit for my 07 EJ2.5. Looks great and gives the engine bay a cool look. Thanks PRE!

You can tell that it's hand built, measured, blueprinted, and not just slapped together using random specs. That shines through even more so when you use this motor. Been running this motor on my 04 Forester XT and it doesn't quit even after 8 years and 80k miles now on the motor. Couldn't be happier making 350whp and 400ft/lbs of torque and without fail it puts a smile on my face to this day!

This was another great purchase. My car is has basic intake and cat back mods with the OTS stage 1+. That stumble drive me insane. I wasn't ready for upgraded fuel system as my plan is to turbo and fuel upgrades at the same time. This kit is well designed and does not dig into the budget for the simple freedom away from the notorious stumble.

The AOS is fantastic. Fast shipping. Easy to install and I could honestly see and feel a difference just putting around town. I feel confident even more now to continue future upgrades.

Good product and quick shipping
