    ⭐️⭐️⭐️⭐️⭐️ Excellent Seller – Highly Recommended! I purchased a bumper valance and had a great experience from start to finish. The item arrived exactly as described—brand new, well-packaged, and in perfect condition. Shipping was faster than expected, and the seller was very responsive and courteous throughout the process. Quality part, smooth transaction, and great customer service—what more could you ask for? Would definitely buy from this seller again!

  • Nice touch to your intake system

    Do not expect any crazy gains with this part but I have noticed a slight increase in fuel economy, and slightly better acceleration on my F150. The spacer whistles between the 1500 to 2800 rpm range as your accelrating, some may not like that, I do though. Airaid is a great company with quality parts I have used on every truck I have owned in the past 10 years

    When you buy this throttle body spacer don’t think it’s gonna give you a lot of power but it’s does make a difference that you will feel i buy this product don’t even have two weeks with it and I love it. Recommend this product to everyone.

  • great product

    for an aftermarket product that did not cost a lot of money I am surprised at how much more power you get from it. It also makes the engine and exhaust sound better.
