What's included
You'll re-use your original electronics, ECU and wiring. Anything else visible in the photos is included unless noted.
Fitment
Interchanges with a number of U.S.-market K-series applications; confirm fitment with your mechanic before ordering. In some applications it installs as a long block with your original external accessories transferred over. Our team is glad to help you check compatibility.
Warranty & returns
This is a performance engine — an upgrade over the engine it replaces in most applications — and it carries our 30-day performance-engine warranty and a 30-day return window, not the 90-day start-up warranty that applies to like-for-like replacement engines.
