Frequently Asked Questions

Is this a true bolt-on intercooler?
Yes — designed to replace the factory cooler on 4N15 Triton and Pajero Sport using OEM mounts and hose locations. No cutting or welding for stock routing.
Do I need a tune after installing?
No tune is strictly required. A calibration can unlock more gains by optimising boost, fueling and timing to take advantage of lower IATs.
What boost pressure can it handle?
The FLEX monoblock core is rated up to 80 PSI. Safe boost depends on your turbo, clamps/couplers, and overall installation quality.
Will it work with my existing piping?
Yes — built around OEM routing. Aftermarket piping kits that move outlet positions may need minor tweaks.
Which models/years does it fit?
Mitsubishi Triton MQ/MR 4N15 (2015+). Pajero Sport QE/QF/QG 4N15 (2015+). If unsure, message us your VIN to confirm.
What’s the typical lead time?
In stock: ships same/next business day. If out of stock: typically 2–4 weeks from Thailand stock. Contact us for current ETA.
