Introducing the Naturally Aspirated Engine Performance Tune Package - expertly and independently developed by OZ Jimny, The File Service & Legendex.
Suzuki put together a fantastic little off-road vehicle with the 2018+ JB74W Jimny, however, there is one common thought from customers worldwide - "Wow that's slow!".
This package is for those who want a noticeable increase in power and torque, but don't want to go down the costly Forced Induction route. And unlike other product manufacturers in the Jimny space, our end results are a true reflection of independent dyno testing with unaltered end-result Power & Torque figures represented against Baseline testing of the same completely stock Manual Transmission Jimny with stock tyres and wheels.
After the Baseline was established, each hardware component was added and retested to unsure true performance gains were achieved before engaging in the final Tuning process as an upgrade collective. We opted for all quality "bolt-on" application items for ease of installation.
The sequence used was:
- Stock vehicle with 98 RON BP Fuel
- Vehicle with Legendex 2.5" Catback Exhaust System
- Vehicle with Legendex 2.5" Catback Exhaust System + Legendex Performance Exhaust Manifold with Catalytic Converter
- Vehicle with Legendex 2.5" Catback Exhaust System + Legendex Performance Exhaust Manifold with Catalytic Converter + aFe Momentum GT Cold Air Intake System
- Vehicle with Legendex 2.5" Catback Exhaust System + Legendex Performance Exhaust Manifold with Catalytic Converter + aFe Momentum GT Cold Air Intake System + Tuning of the factory ECU
Not only did we see a peak Torque figure increase of 13.56% and peak Power figure of 12.85%, but gains across the entire rev-range translating to a noticeable "real world" driving improvement:
*Please note - the Automatic Transmission Jimny made less power due to the tuning difficulty of the Auto Gear Box on the Dyno, however underwent the same process as stated above.
