The OEM charge-air-cooler manifold for the B58 engine is adequate in cars with little or no modifications. However, it starts to really its weaknesses in cars that have bolt-on modifications, turbo upgrades, increased fueling (such as port injection), and performance tuning. In addition, the OEM intercooler system has been known to suffer from heat soak in demanding racing conditions such as time attack, endurance racing, drag racing, and drifting, as well as spirited driving on the street. This can cause the car to pull timing out of the engine due to high intake air temperatures (IATs). This can send the car into "limp mode" once temperatures reach a certain threshold. In high boost applications the OEM manifold is also prone to failing at the crimp on gasket joining of the core and tanks.This Part Fits:

Light, comfy, and a brand you can trust with your feet
Size: 3.5 Big Kid, Color: Black/White
My son tears through shoes and somehow they're perpetually untied, no matter what we do. These are great as they don't need to be tied but look laced up, are very light and cushiony, and just look great so they go with everything. Saucony is also a great trusted brand that I've run a few marathons in myself, so I figured, let's try a pair and see how long they last. It's only been a few days but I'm getting good reviews from my son and they're his new go to pair.

Great shoe seems supportive

Bought the shoe because it was recommended by a podiatrist for young kids and I'm pleased with what seems like good support.

Good fit. Good support. Good for my new runner!
The quality definitely meets our expectations. The price point is pretty good; I can't swallow adult-sized prices for kid-sized shoes. Delivery was early...which my son really appreciated!

Falling apart
Size: 5 Big Kid, Color: Teal/Periwinkle, Size: 5 Big Kid, Color: Teal/Periwinkle
I bought these two weeks ago for my daughter to train and use for a mini triathalon she is doing and the sole tread are already coming apart in several areas. Including the toe. Not worth the money
