G4FA Engine Replacement: Hyundai and Kia 1.4 MPI

The Phone Call That Ruins Your Month

Your mechanic just said "G4FA" and then a number. The number probably started with a four or five. Thousand, not hundred.

You're now Googling at midnight to find out whether your Hyundai i30 is worth saving. Welcome to the club nobody joins voluntarily. We sell the membership fees—factory-new engines that work.

What "Your G4FA Is Gone" Actually Means in Euros

When a mechanic pronounces death on a G4FA, it can mean one of three things happened inside your 1.4-litre four-cylinder:

Timing chain catastrophe. The tensioner wore out, the chain skipped, and your valves met your pistons in a violent first date. A rebuild can cost more than a new engine.

Oil starvation. Those piston rings that were "a bit tired" finally gave up. The engine consumed its own oil between services, bearings ran dry, and now there's metal where metal shouldn't be.

Connecting rod departure. Something broke, punched a hole in the block, and created what mechanics poetically call "catastrophic internal failure." Your engine is now a very expensive paperweight.

The translation to euros: the card below shows the current price of a factory-new G4FA engine. Installation adds €600-€1,200 at independent Irish garages (€60-€100/hour for 10-12 hours of work).

Your Three Options (And What Each Actually Costs)

Option 1: The Rebuilt G4FA

What they promise: "Professionally reconditioned" engine for €2,170-€4,077 (based on 493 listings tracked on Motorinsel.eu).

What you get: An engine that's been opened by someone. Maybe a specialist. Maybe someone less qualified. New gaskets, possibly new bearings, definitely the same block that already failed once.

The hidden cost: 90-day warranty that covers "manufacturing defects" but not "the thing that actually breaks." Read the exclusions before you buy.

Real total: €2,500-€4,500 installed.

Option 2: Factory-New from Hyundai/Kia Dealer

What they promise: Genuine Hyundai/Kia G4FA with full manufacturer backing.

What you get: A factory-new engine like ours, blessed by the dealership and priced like it includes the building.

The price reality: €4,000-€5,500 for the engine alone (industry estimates—dealers rarely advertise parts pricing). Installation at dealer rates adds €1,000-€1,680 (€100-€140/hour for 10-12 hours).

Real total: €5,000-€7,200 installed.

Option 3: Factory-New from Majestic Engines

What we promise: Factory-new G4FA, never installed, 12-month commercial warranty, in stock now.

What you get: Exactly that, at the price on the card above, including VAT. Delivery in 2-4 business days. Fits your i20, i30, ix20, Accent, Ceed, Rio, or Venga.

The hidden cost: There isn't one. The price you see is the price you pay.

Real total: the engine price plus €600-€1,200 for installation.

Option 4: Used G4FA Engine

What they promise: Low-mileage engine for €1,500-€2,800 depending on kilometres.

The market reality (from eBay Europe, German and Spanish breakers):

• Under 80,000 km: €2,000-€2,800
• 80,000-150,000 km: €1,540-€2,250
• Over 150,000 km: €998-€1,700

The gamble: You're buying someone else's wear, someone else's oil change schedule, someone else's problems. Warranty is typically 30-90 days—enough time to install it, not enough time to know if it'll last.

When it makes sense: If your car is worth under €2,500 and you're selling it soon anyway. Otherwise, you're paying used prices for used reliability.

The Mathematics Nobody Wants You to Do

Let's compare your actual options with actual numbers:

The maths are simple: compare the price on the card with the dealer and reconditioned quotes above, then compare the warranties.

Your i30 with 150,000 km and a new engine is worth more than your i30 without an engine. It's also worth more than a different i30 with 120,000 km and an engine you know nothing about.

The used car comes with someone else's maintenance history, someone else's driving style, and someone else's problems waiting to surface. Your car only has one problem, and we're selling the solution.

G4FA Engine Specifications (For the Research Phase)

The G4FA is a 1.4-litre inline-four petrol engine from Hyundai/Kia's Gamma family:

• Displacement: 1,396 cc (1.4L)
• Configuration: Inline 4-cylinder, DOHC, 16-valve
• Technology: CVVT (Continuously Variable Valve Timing)
• Power output: 66 kW (90 PS) to 80 kW (109 PS) depending on tune
• Fuel type: Petrol
• Production years: 2007-present

Fits these vehicles:

• Hyundai Accent IV
• Hyundai i20
• Hyundai i30
• Hyundai i30 Coupe
• Hyundai ix20
• Kia Ceed
• Kia Pro Ceed
• Kia Rio III
• Kia Venga

Hyundai and Kia fitted several of these models with 1.6 engines too, including the G4FD with direct injection. Read the code on the engine block before you order. Our guide to G4FD engine problems shows how to tell the codes apart.

When to Replace vs. When to Walk Away

Replace the G4FA if:

• Your car has less than 200,000 km on the body/chassis
• No significant rust or structural issues
• Transmission works properly
• You like the car and know its history
• The math works (car value + engine cost < replacement car cost)

Consider walking away if:

• Multiple major systems failing simultaneously
• Severe rust compromising structure
• Car value is genuinely less than €2,000
• You've been looking for an excuse anyway

For most i30, i20, Ceed, and Rio owners, the G4FA replacement makes financial sense until the car hits about 250,000 km or develops problems beyond the engine.

The Bottom Line

Your G4FA died. The card above shows what a factory-new replacement costs today. Dealers charge €4,000-€5,500 for the engine alone, by industry estimates, and a quality reconditioned unit comes with a fraction of the warranty.

We stock G4FA engines. Delivery takes 2-4 business days. They come with a 12-month commercial warranty that doesn't require a legal team to interpret.

Factory-new. Full warranty. In stock. Shipping to Ireland, Belgium, Netherlands, Denmark, Sweden, Finland, France, and Spain.
