LN Engineering Engine Oil Pan
LN Engineering 99 0141 020 Deep Sump Oil Pan Kit for Porsche 911 Boxster Cayman
LN Engineering Engine Oil Pans: Engineered to Keep Porsche Engines Alive on Track
For Porsche enthusiasts who push their cars on a circuit, oil starvation is one of the most serious — and preventable — engine killers. LN Engineering, founded in 2002 and widely regarded as a leader in the Porsche aftermarket, has developed a targeted answer to this problem through their deep sump engine oil pan kits, offered under their Bilt Racing Service (BRS) brand. These are not generic bolt-on accessories — they are precision-engineered solutions developed with real-world track data and built to a standard that meets or exceeds OEM requirements.
Why the Factory Oil Pan Falls Short
High-g cornering, sustained track sessions, and elevated ambient temperatures all conspire to push a stock Porsche oil pan beyond its design limits. Oil sloshes away from the pickup tube under lateral loads, leading to momentary — and sometimes fatal — oil starvation events. Making matters worse, later-generation Porsche engines compound this vulnerability with an additional design flaw: the factory oil pan on 991.2-generation engines is made of plastic, leaving it susceptible to road hazard damage that can result in catastrophic oil loss.
Bilt Racing Service Deep Sump Oil Pan Kits
LN Engineering's BRS deep sump kits directly address both the capacity and construction weaknesses of the factory pan. Key products in the lineup include:
- BRS 2QT Deep Sump Kit for MY97–08 M96/M97 engines (Boxster, Cayman, 911 996/997): Based on the factory Porsche X51 oil sump plate concept, this kit increases oil capacity by 2 quarts and includes an improved X51-style oil baffle and anti-slosh tray, along with a pickup tube extension and Genuine Porsche 997 oil return tubes to ensure oil is returned from the cylinder heads as quickly as possible.
- BRS Billet 2.5QT Deep Sump Kit for MY09–16 9A1 engines (987.2, 997.2, 981, 991): A one-piece billet aluminum deep sump that restores oil fill quantity to the 9.5–10 quart range — critical for the later direct-injection 9A1 engines used across the Boxster, Cayman, and 911 model lines.
- BRS Billet 2QT Deep Sump Kit for 718 4-Cyl Models (MA2.20/MA2.22 engines): Machined from billet aluminum rather than cast, this kit for 2016 and later 982/718 Boxster and Cayman models has been shown to lower oil temperatures on track by up to 40 degrees Fahrenheit — proven in real racing conditions by Tatum Racing, where the additional 2 quarts of capacity eliminated recurring heat-related limp-mode events.
- BRS Billet 2.5QT Deep Sump Kit for MY17+ 991.2 (MA2 engine): In addition to the thermal and capacity benefits, this billet aluminum pan directly replaces the stock plastic pan, providing significantly greater structural strength against road hazard damage — a must for any 991.2 owner who takes their car to the track or drives on imperfect road surfaces.
Design and Construction Philosophy
Every LN Engineering deep sump oil pan is machined from billet aluminum — not cast — which means tighter tolerances, superior strength, and consistent material integrity. Kits are designed as complete systems, including oil pickup tube extensions, custom stainless baffles, and all required hardware and sealants, so there is no guesswork involved in installation. The X51-style baffle and anti-slosh tray designs keep oil concentrated around the pickup tube during the sustained lateral forces of track driving, dramatically reducing the risk of oil starvation-related engine failure.
For Porsche drivers who are serious about protecting their investment — whether on the street or the circuit — LN Engineering's engine oil pan offerings represent one of the most well-engineered and track-validated upgrades available in the Porsche aftermarket.
