Honda Fit L15A1 1.5L L4 Engine 12491E 2006-2008

Description

Restore crisp subcompact acceleration with this precision-machined Honda Fit L15A1 Remanufactured Engine. Each 1.5L 4-Cylinder 16-Valve SOHC long block features diamond-surfaced aluminum deck surfaces and line-honed main bearing saddles. Technicians must perform pressurized oil priming prior to initial cranking and execute an exact 500-mile break-in oil change to protect the VTEC rocker arm assemblies from premature contact wear.

Engineered with open-deck aluminum block casting RME, this compact power plant features centrifugal cast iron cylinder liners align-honed for crankshaft centerline concentricity. The rotating assembly pairs a micro-polished forged steel crankshaft with forged steel connecting rods and hypereutectic pistons with anti-friction skirt coatings. The 16-Valve SOHC cylinder head receives diamond deck resurfacing for head gasket retention. Net dry weight totals 250 lbs inside crated dimensions of 36in length by 36in width by 36in height. Sump capacity measures 3.8 quarts.

Key Features of Honda L15A1

Automotive repair technicians buy Honda L15A1 remanufactured engine long blocks to resolve lost compression and restore original fuel economy ratings. This long block replacement provides factory-matched machine tolerances for transverse front-wheel-drive subcompact hatchbacks.

• VTEC rocker arm assemblies undergo ultrasonic cleaning and clearance checks to guarantee high-RPM valve engagement.
• Block casting RME sleeves receive diamond plateau honing to establish an Ra 14 finish.
• Micro-polished crankshaft journals eliminate runout to protect bi-metal engine bearings under continuous load.
• SOHC 16-Valve cylinder heads undergo CNC multi-angle valve seat cutting to maintain 0.001in runout.
• Align-honed main bearing tunnels preserve bearing crush and circularity under elevated engine speeds.
• Multi-layer steel head gaskets ensure combustion chamber seal integrity under elevated thermal load cycles.
• New high-grade cylinder head bolts supply uniform clamp loads across the aluminum engine block deck.

Dyno Load Operational Tolerances Specifications

Dyno cell spin testing verifies mechanical oil gallery pressurization and power output prior to crate packaging. The 1.5L 1497cc SOHC VTEC engine outputs 109 HP at 5,800 RPM and 105 ft-lbs of shaft torque at 4,800 RPM. Crankshaft main journal oil clearance holds between 0.0010in and 0.0014in, while connecting rod clearance measures 0.0011in to 0.0014in. Individual cylinder compression gauges verify 185 PSI across all 4 cylinders. Hot engine oil pressure maintains 55 PSI at 3,000 RPM with regulated coolant operating temperatures steady at 190°F.

Vehicle Fitment Drivetrain Guide

This long block fits 2006 to 2008 Honda Fit 5-door subcompact hatchbacks equipped with the 1.5L 1497cc SOHC L15A1 engine and block casting RME. Drivetrains require transverse front-wheel drive paired with a 5-Speed manual transaxle or 5-Speed automatic transmission. This assembly does not fit 2nd-generation 2009 to 2014 Honda Fit L15A7 i-VTEC platforms, hybrid LEA1 chassis, or 1.3L L13A models due to distinct intake manifold ports, electronic throttle bodies, and cylinder head casting revisions.

Installation Protocol Service Requirements

Technicians must inspect intake manifold gaskets, verify electronic throttle body cleanliness, and purge cooling air from the heater core circuit during engine install. Operational warnings restrict use in custom turbo applications exceeding 6 PSI boost on stock compression pistons or non-vented track chassis lacking auxiliary oil coolers.

• Pre-fill the spin-on oil filter and prime the lubrication circuit with 5W-20 synthetic blend oil.
• Drain initial break-in oil and install a replacement oil filter at the 500-mile service point.
• Check mechanical valve lash clearances on intake and exhaust rockers at 1,500 miles.

Warranty Terms Core Return Policy

This long block carries our standard 3-Year Unlimited-Mile warranty for reliable road service. We provide free prepaid return freight shipping for your depleted rebuildable core engine within a standard 30-day window. The crated assembly contains the remanufactured long block, complete timing chain drive, oil pan, and valve cover.
