2006 Honda Civic 1.8L R18A Engine for Sale
$749.00
-
The 2006 Honda Civic came equipped with the R18A 1.8L SOHC VTEC engine, known for strong reliability but prone to timing chain tensioner wear, blowing head gaskets, and oil consumption past 100k miles on the original US-spec unit. Our JDM R18A replacement is sourced from a low-mileage Japanese Civic (typically 50,000-75,000), tested, and visually inspected before it ships, and is a bolt-in fit for 2006–2011 Civic LX, EX, and DX trims — no ECU or wiring modifications required.
These are factors which make these engines perfect replacements for your dying Honda Civic.
