AEM Universal 52mm Digital Oil Pressure Gauge 0-150 PSI

AEM Digital Oil Pressure Gauge - 0-150 PSI

Tracking your turbo Civic or all-motor Integra and you're worried about oil starvation at high RPM? The AEM digital oil pressure gauge reads from 0-150 PSI in 1 PSI increments so you know exactly what's happening with your oil pressure. It's got a three-digit LED readout in the center and 24 green LEDs around the edge that light up like a sweeping needle. When your oil pressure drops, you'll see it immediately. The gauge auto-dims at night so it's not blinding you, and it comes with a 0-5V analog output so you can wire it to your Hondata, AEM standalone, or whatever data logger you're running. If you're doing track days or road racing and you want to make sure your oil pressure isn't dropping off at 8500 RPM in Turn 9, this gauge tells you what's actually happening instead of guessing.

Here's Why Oil Pressure Matters on Track

Your stock oil pressure gauge is garbage. It's either showing you nothing or it's showing you some vague needle position that doesn't tell you the actual pressure. When you're pulling high Gs in corners or you're revving to 9000 RPM, your oil pressure can drop if your oil pump can't keep up or if you're running low on oil. If your pressure drops below 20-30 PSI at high RPM, you're starving your rod bearings and main bearings. That's how you spin a bearing or crack a rod. The AEM gauge shows you the exact pressure in real time. If you see it dropping into the danger zone on track, you know to back off before you grenade your motor. Your stock gauge won't tell you that until it's too late.

24 Green LEDs Work Like a Tach

The gauge has 24 green LEDs around the edge that work like a shift light or tach. As your oil pressure increases, more LEDs light up. You can see the LEDs in your peripheral vision while you're driving, so you don't need to stare at the center number. If the LEDs start dropping off, you know your pressure's falling and you need to check what's going on. It's way faster to glance at the LEDs than to read a number while you're mid-corner at 100 mph.

0-5V Output for Data Logging

The gauge has a 0-5V analog output that you can wire to your Hondata S300/KPro, AEM Infinity/Series 2 EMS, AEM AQ-1 data logger, or pretty much any standalone ECU or data logger. That lets you log oil pressure alongside AFR, coolant temp, oil temp, and boost pressure. After your session, you can pull the logs and see exactly where your oil pressure dropped and what you were doing when it happened. Maybe it's dropping in long right-handers because your oil's sloshing away from the pickup. Maybe it's dropping at 8500+ RPM because your oil pump's cavitating. The logs tell you what's actually wrong instead of guessing.

Auto-Dims So You're Not Blinded at Night

The gauge has a built-in photocell that adjusts the LED brightness based on how much light's hitting it. During the day, the LEDs are bright so you can read them in sunlight. At night, they dim automatically so you're not staring at a blinding green display. You don't need to wire it to your dimmer switch or mess with brightness settings - it just works.

Works With

• Carbureted and EFI vehicles
• Hondata S300, KPro, FlashPro (0-5V analog input)
• AEM Infinity ECU (0-5V analog input)

• AEM AQ-1 Data Logger (0-5V analog input)
• Most aftermarket data loggers and standalone ECUs that accept 0-5V analog inputs

Note: The brass oil pressure sensor screws into your oil pressure sender port on your engine block or oil filter housing. You're ditching your factory oil pressure sender and running the AEM sensor instead. Some engines have multiple oil pressure ports - use the one closest to your oil pump for the most accurate reading. The 0-5V analog output needs to be wired to your ECU or data logger if you want to log oil pressure. If you're just using the gauge for visual monitoring and you're not logging, you don't need to hook up the analog output. Mount the gauge where you can actually see it while you're driving. Don't stick it down in the footwell or way off to the side. Oil pressure drops happen fast and you need to catch them immediately or you're done. If you're running a baffled oil pan, an Accusump, or an oil cooler, this gauge is mandatory. You need to know your pressure's staying up when you're pulling Gs or revving high.
