❓ FAQs

How much power can the PKS 46mm support?
With correct fueling, intercooling and a quality tune, it supports 300+ rwhp.
Will it bolt to my factory manifold?
Yes — it suits most 1KD and 4JJ1 factory manifolds. Some builds may need small adjustments or fabrication.
Do I need upgraded injectors?
For moderate power levels, stock injectors may cope. For high-power goals (300+ rwhp), larger injectors are recommended.
