The Holden 2012 LFX V6 might not always get the spotlight, but when tuned right, these engines deliver seriously impressive gains. Today’s feature is a perfect example of how much potential is hiding inside the 3.6L LFX — all it needs is the right breathing mods.
This customer came in looking for better throttle response, more mid-range punch, and a bit more excitement behind the wheel. And with a few key upgrades, that’s exactly what they got.
🔧 The Setup: Breathing Mods Done Right
To unlock the LFX’s potential, the following upgrades were fitted:
Full Exhaust System — opens up flow while adding a cleaner, deeper tone.
High Flow Cats — reduces restriction and helps the V6 breathe more efficiently.
ORSSOM OTR Intake — one of the best bang-for-buck intakes for Holden V6s.
These mods work together to improve airflow on both the intake and exhaust side. For naturally aspirated engines like the LFX, air is everything — the more efficiently it flows, the more power you make.
📈 Before & After Dyno Results
Before Mods:
348 Nm @ 110
166.8 kW @ 210
After Mods:
400 Nm @ 134
198.2 kW @ 220
That’s a +52 Nm torque increase and a +31.4 kW gain — extremely solid numbers for a naturally aspirated V6. What’s even more impressive is where the gains sit.
💡 What These Numbers Really Mean
Power gains are great, but drivability is where these upgrades shine.
🔥 Stronger Mid-Range Punch
The increase in torque at 134 km/h shows how much harder the LFX pulls through the middle of the rev range — perfect for overtaking or spirited driving.
⚡ Sharper Throttle Response
With better airflow, the engine reacts faster. Low-RPM hesitation is reduced, making the car feel more alive and responsive.
🎶 Cleaner Exhaust Note
The upgraded exhaust and cats give the V6 a more refined and aggressive tone without being overly loud or droney.
📦 More Efficient Power Delivery
The ORSSOM OTR helps deliver cooler, denser air which the ECU loves — especially when paired with a solid tune.
🏁 Final Thoughts
The 2012 LFX V6 may not have the badge of a V8, but don’t underestimate what the right setup can do. This build proves that with a quality exhaust, high-flow cats, and an OTR intake, the LFX becomes a much more capable and enjoyable engine.
For owners looking to wake up their V6 without going forced induction, this mod combo is one of the best value paths you can take.
