Works with Factory 74mm Throttle Body

The perfectly balanced mid engine Cayman is Germany's canyon carving track meister. Unfortunately, the Cayman was delivered slightly under powered from the factory so as not to threaten the Carrera's thrown. The Cayman IPD intake plenum delivers increased performance that puts the Cayman in the ring with the Carrera.

The IPD Plenum out performs every other intake system on the market. Don't be fooled by other competitors claiming to offer Plenums. All factory Porsche air distributors are of the "T" variety and therefore suffer from less than ideal air flow and intake air speed.

The genius and power behind the IPD plenums comes from the patented "Y" style design and optimized diversion areas to deliver real and impressive power that will transform your Cayman's performance and heighten your Porsche driving experience.

The 74mm Cayman S Plenum utilizes the factory 74mm throttle body. This version provides impressive power gains throughout the entire power band, especially in the midrange where it's most critical and most enjoyed.

The 74mm Cayman S Plenum application is recommended for Cayman enthusiasts looking for considerable performance gains without pushing the performance envelope. Max horsepower is 14 and max torque is 12 which all comes in around 5600 RPM. Power gains are realized throughout the entire power band without any loses in power.

The IPD Cayman S Plenum will provides the most impressive power gains of any engine upgrade available and will truly transform your Cayman driving experience. The 74mm IPD Plenum is the best Cayman modification on the market and will further compliment other mods such as exhaust, software and beyond.

    Perfect Mini Backpack for almost any occasion! Fits 11 inch ipad
    Color: Black, Color: Black
    Giving 5 🌟🌟 🌟🌟🌟, even if I havent used it yet! because it: -arrived in perfect good packaging, protected and nothing missing. -11 inch ipad fit with its own pocket(although it did reach the very top of the bag and can feel its corners) - can fit 2 regular plastic bottled water on both sides - coin pocket(tho I'll be putting coffee candies and mint instead) - spacious enough for mini snacks or notebook/light books. - has 2 pockets inside - 3 pockets outside(1 at back, 2 at front) Good value for money. Good for travels!(be using for camping). And I think its water resistant. It is a simple, cute, very functional bag for many occasions Wish: that the strap would be a bit longer, although I did have extra 2.5 inches before it rested comfortably at my lower back.

    Great Medium-Sized Backpack !
    Color: Khaki
    This is the best medium sized backpack ! Bought it mainly for that it fit my Kindle since a smaller backpack didn't and the multiple compartments (more than I need but easy access). Lightweight, water resistant, great value and the quality so far is great. I especially like the locking feature should I need it. It's much lighter than my travel purse (PacSafe that I would still use for travel, especially international.) The "security" feature is an added compartment for more local travel.

    Great bag, short shoulder straps
    Color: Black
    Love the size and the many, many pockets. The quality is great, it's really well made. But the shoulder straps are short. Like for a little kids backpack short. I love the bag so much I'm getting a kit to extend the should straps. But yeah 5 stars for the bag, minus 2 for the short shoulder straps.

    Great mini backpack
    Color: Black
    I love this backpack purse! It has so many pockets; 2 side pockets great for water bottles, umbrella, or my sunglass case. And I love the safety features. The only reason I gave it 4 stars instead of 5 is that the adjustable straps sometimes slip out. I will need to bring it to the shoe repair shop to have one more fold sewn into the end of the strap to prevent it from continuing to slip out.
