PLM Pro Throttle Bodies are designed to be used with factory intake manifolds as well as aftermarket Intake manifolds for bolt-on horsepower and torque gains by optimizing engine airflow, all at a competitive price.

The B-Series 74mm throttle bodies are 14mm larger in diameter than the OEM 60mm throttle body. The throttle bodies are precision die-cast from high-quality materials with an idle adjustment screws for fine tuning. Each Throttle Body features an oversized bore, which results in significant horsepower gains throughout the power band on naturally aspirated applications and even more on forced induction ones. This results in a larger opening for incoming air and dyno proven 15+ WHP gains (modified engine with port matched intake manifold opening). Some vehicles may require customizing of coolant lines. We recommend port matching the intake manifold to have the best result.

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
