Requires use of 74mm Throttle Body (Sold Separately)

The 986 Boxster marked Porsche's return to a purpose built 2 seat roadster, since the famed 550 Spyder. This liberating open cockpit platform was instrumental in saving Porsche from financial uncertainty and was their highest volume seller from 1997 to 2003.

The perfectly balanced mid-engine 986 Boxster was designed to deliver driving excitement on winding roads while enabling the driver (and passenger) to take in the sights of the surrounding environment while listening to the intoxicating mechanical symphony of the flat 6 exhaust soundtrack.

The feel of a Boxster can only be further heightened by adding improved performance. The IPD Plenums provide impressive net power and torque gains throughout both power bands making for an even more visceral Porsche driving experience.

All 986 Boxster IPD Plenum applications are designed to utilize the larger 74mm Porsche throttle body. The combination of the patented "Y" designed IPD Plenum combined with a larger TB, allows for improved airflow and intake air velocity. Porsche wants the Boxster to perform, just not so well that it competes with more “prestigious” models. Controlling (aka Reducing) engine output has effectively been achieved by simply choking the inlet air with smaller throttle bodies, preventing peak power from being realized.

The IPD Plenum is the absolute single best performance mod you can install on a Porsche Boxster. Installation of this plenum is relatively straightforward although IPD strongly recommends the install be performed by a qualified Porsche technician. The Plenum comes with our custom silicone hose that fits the larger 74mm TB as well as additional hardware to complete the installation. The only additional component required is the 74mm Throttle Body which can be purchased separately below.

The 986 Boxster S 3.2L Plenum provides impressive net performance gains throughout both power bands, especially in the midrange where we all want and enjoy it most. The Boxster S Plenum and upgraded 74mm (from 68mm) throttle body package is an absolute must for enthusiasts looking to elevate the driving experience of their vehicle to the next level. Power gains are 15+ wheel HP and 15+ wheel TQ with net gains being realized from launch to redline. This is the perfect upgrade for both stock and modified Boxsters with no ECU modifications necessary.

Custom IPD Silicone hose is included with the purchase of Plenum.

    Discovered latex and thrilled
    Size: Queen
    Bought a Beautyrest mattress in late 2021 that now is uncomfortable and has dips. Beautyrest would reject the 10 year warranty due to a single stain on mattress (based on their policy), so I didn't even bother. So, I pondered if I should order a new one and which one. In the process I found out latex toppers may save the day. Talatex medium firm mattress in queen size was received within a week and a half and installed on top of existing Beautyrest mattress. Since then, no pain in hips, no sweating at night, no neck problems. My daughter tested it one night with me, and since then wants to sleep on my bed and not hers, so this is really reviewed by two people. Excellent product!! Has a bounce but you don't sink in it (two mattresses ago, I had a 13" high end high density visco elastic memory foam mattress where sinking into it happened). When I can afford, I will buy a 4" latex topper firm and install that under the existing 2" Talatex medium firm over a slatted base. I'll do away completely w/ the mattress I'm using now.

    Does not provide much pressure relief
    Size: Queen
    It does keep you cooler/neutral. It needs to be a little denser. When you are on it, it goes pretty flat. It does help some but my hip needs a little more support that this offers. Be aware, the cover has a coating of fire retardant. We asked them to send one without the toxic chemicals. (Personal choice)

    Forget about the memory foam!
    Size: Twin 3 Inches
    My sleep quality is fantastic on this thing, and I don’t even sweat like a memory foam cover! I was scared to spend the money but I’m glad I did! It’s really helped my back and overall pain, as it rises to fit the empty spaces left by flat firm mattresses.

    Pretty Good
    Size: Queen
    The product arrived at my street address instead of my PO Box address last minute - without me getting prior notice that it was to large to be delivered to post office. Not sure why the seller did not notify me and let me know what was happening. The quality of the latex topper itself is good, covering nice with a zipper to take off and wash. There was no smell after about 5 minutes of coming out of the packaging. I am using it as extra padding for a new mattress which is pretty firm. After sleeping on it last night it helped just enough - perhaps someone who needs a little more cushioning should get the 3" topper version.

    Soft and comfortable.
    Size: King 3 Inches
    The packaging was big and heavy and required 2 persons to move. The pad is soft and very comfortable. The latex had a bit of smell, but not too bad. Overall I am satisfied with the product.
