If you own a Skoda Kushaq, Rapid, or Slavia with the 1.0-litre TSI engine and you have found the NGK IKER7A8EGS listed as a "Set of 4" — stop before ordering.
The 1.0 TSI is a 3-cylinder engine. It needs exactly 3 spark plugs, not 4. This is the single most common and entirely preventable ordering mistake for this car.
In short: The NGK IKER7A8EGS (stock no. 94224, VW/Skoda OEM cross-reference 04E905602D) is the Laser Iridium spark plug for the Skoda Kushaq, Rapid, and Slavia 1.0 TSI. Order 3 plugs per car. The 1.5 TSI variants of the Kushaq and Slavia use a completely different plug — the IKER7A8EGS does not apply to them.

What Is the NGK IKER7A8EGS?
The IKER7A8EGS belongs to NGK's Laser Iridium series — the OEM co-development tier engineered directly with vehicle manufacturers for specific engines. It features a laser-welded iridium centre electrode and a platinum disc on the ground electrode, matched to the exact ignition requirements of the VW Group 1.0L TSI EA211 turbocharged direct-injection engine.

Which Skoda Cars Use the IKER7A8EGS?
Sourced from the official NGK India 4-Wheeler Iridium Application Chart.
| Vehicle | Engine | Cylinders | Plugs Required |
|---|---|---|---|
| Skoda Kushaq 1.0L | 1.0L TSI EA211 (3-cyl) | 3 | 3 |
| Skoda Rapid 1.0L | 1.0L TSI EA211 (3-cyl) | 3 | 3 |
| Skoda Slavia 1.0L | 1.0L TSI EA211 (3-cyl) | 3 | 3 |
All three models use the same 1.0L TSI 3-cylinder engine assembled at VW Group's Chakan plant in Pune. The engine specification and plug requirement are identical across all three.
What about VW Taigun, Virtus, and Polo GT TSI? Multiple authorised Indian parts retailers list the IKER7A8EGS for these models under the same VW OEM cross-reference 04E905602D — which makes sense, since the 1.0 TSI EA211 engine is the same across the MQB A0 IN platform. However, VW India owners should verify fitment independently through a VW authorised service centre or the NGK India application chart before ordering, as the NGK India chart lists this plug specifically under Skoda Auto India.
⚠️ Why "Set of 4" Is the Wrong Quantity for Your Car
The 1.0 TSI has three cylinders. Three cylinders = three combustion chambers = three spark plugs. This is fixed physics — it does not change by variant, trim level, or transmission.
The "Set of 4" in the product name is a packaging format used across multiple VW Group applications — including 4-cylinder engines that genuinely need 4 plugs. For your 1.0 TSI Skoda, one plug in that box will always be unused.
Practical guidance for ordering:
- If the platform offers individual units — order 3
- If only a Set of 4 is available — order 1 box and accept the surplus plug
- For fleet or bulk servicing — calculate based on 3 plugs per car, not 4
Installing 3 plugs in a 3-cylinder engine is correct and complete. The fourth plug is not a spare — it is simply not needed.
⚠️ Critical: 1.0 TSI vs 1.5 TSI — Confirm Your Engine Before Ordering
Both the Kushaq and Slavia are sold with two petrol engine options in India:
| Engine | Displacement | Power | Cylinders | Plug |
|---|---|---|---|---|
| 1.0L TSI | 999cc | 115PS | 3 | IKER7A8EGS — this article |
| 1.5L TSI | 1,498cc | 150PS | 4 | Different plug — IKER7A8EGS does not apply |
The 1.5 TSI is a different engine with different ignition requirements. The thread size is the same (12mm), but the heat range, gap, and electrode specification are different. Installing the IKER7A8EGS in a 1.5 TSI is an incorrect fitment.
To confirm your engine:
- Owner's manual or registration certificate: 999cc = 1.0 TSI; 1,498cc = 1.5 TSI
- Power output: 115PS = 1.0 TSI; 150PS = 1.5 TSI
Do not order based on the model name alone. Kushaq and Slavia are each available with both engines.
Why the 1.0 TSI Needs Laser Iridium — Not a Generic Plug
The VW Group 1.0 TSI EA211 uses turbocharged direct injection — fuel injected directly into the combustion chamber at high pressure. This creates higher cylinder pressures than conventional port-injected engines, demanding reliable, precisely timed ignition across a wide range of conditions.
The IKER7A8EGS's heat range 7, 0.8mm pre-set gap, and laser-welded electrode geometry are OEM co-engineered to the EA211's specific combustion parameters. A generic iridium plug with a matching thread and reach but different heat range or gap is not calibrated to what the engine's ignition system is built around.
GDI engines also accumulate carbon deposits on intake valves over time — a known characteristic of direct injection that is accelerated by the stop-go city driving most Kushaq and Slavia owners experience daily. A correctly specified, serviceable plug reduces incomplete combustion that contributes to this deposit formation.
One 3-cylinder note: in a 3-cylinder engine, a misfiring plug affects one-third of total ignition work — a proportionally larger impact than in a 4-cylinder. A misfiring cylinder produces a noticeable vibration and uneven idle that 3-cylinder owners will recognise immediately. This makes prompt diagnosis and correct plug maintenance more consequential in the 1.0 TSI than it would be in a 4-cylinder equivalent.
When to Replace and What to Watch For
Refer to your owner's manual for the exact interval. Available VW Group service documentation for 1.0 TSI vehicles references spark plug replacement at 30,000–60,000 km depending on the service schedule and driving conditions.
Do not extend the interval informally. The 1.0 TSI's turbocharger and direct injection place higher thermal demands on the plug than a naturally aspirated engine — a worn plug that tolerates itself in a simpler engine will produce perceptible misfires and hesitation in a turbo GDI unit.
Symptoms to watch for in your 1.0 TSI Skoda:
- Rough or uneven idle, especially on cold starts
- Hesitation or stumble during acceleration, particularly at low RPM before boost builds
- Increased turbo lag — delayed power delivery from low speed
- Hard starting in cooler conditions
- Drop in fuel efficiency without a change in driving pattern
- Engine warning light with a misfire code (P0301, P0302, or P0303)
Always scan for fault codes before replacing parts. The misfire code identifies the specific cylinder, allowing targeted inspection of the plug, ignition coil, and injector for that cylinder. Blanket replacement without diagnosis can miss the actual cause.

Buying Genuine Parts — What to Check
The IKER7A8EGS is stocked at Skoda authorised service centres under OEM cross-reference 04E905602D. It is also available through NGK-authorised distributors and reputable online platforms. As with all NGK Laser Iridium products, counterfeits exist — and premium European-platform parts attract proportionally more counterfeit activity because the retail price makes them worth replicating.
Signs of a genuine NGK IKER7A8EGS:
- Part number IKER7A8EGS and stock number 94224 clearly printed on packaging
- VW/Skoda OEM cross-reference 04E905602D on or within the packaging
- "Made in Japan" on both plug and box
- NGK Laser Iridium branding on the ceramic insulator and packaging
- Clean, consistent ceramic finish and precision-machined thread and hex
Buy from: Skoda authorised service centres, NGK-authorised distributors, or verified online automotive platforms with genuine sourcing, seller ratings, and clear return policies.
Avoid: Unknown marketplace sellers, prices significantly below the Laser Iridium market rate, plugs without original NGK Laser Iridium packaging, or any listing that cannot confirm both the NGK stock number and the VW OEM cross-reference.

Conclusion
The NGK IKER7A8EGS Laser Iridium (stock no. 94224, OEM cross-reference 04E905602D) is the correct OEM ignition specification for the Skoda Kushaq, Rapid, and Slavia 1.0 TSI. The 1.0 TSI is a 3-cylinder engine: order exactly 3 plugs per car. The "Set of 4" packaging applies to 4-cylinder applications — for your 1.0 TSI, the fourth plug is unused waste.
The 1.5 TSI variants of the Kushaq and Slavia use a completely different plug. The plug is factory pre-set to 0.8mm and must not be re-gapped. Confirm your engine displacement, order the correct quantity, and purchase from a verified source.

FAQs
Q1: How many NGK IKER7A8EGS plugs does a Skoda Kushaq, Rapid, or Slavia 1.0 TSI need?
Exactly 3. The 1.0 TSI is a 3-cylinder engine. Despite the product being packaged and marketed as a "Set of 4," the correct quantity for one complete service on any 1.0 TSI Skoda is 3 plugs. The fourth plug in the box is unused.
Q2: Does the IKER7A8EGS fit the Skoda Kushaq 1.5 TSI or Slavia 1.5 TSI?
No. The 1.5 TSI is a 4-cylinder engine with a different ignition specification. The IKER7A8EGS is specified for the 3-cylinder 1.0 TSI only. Confirm your engine variant — 1.0 TSI (115PS, 999cc) or 1.5 TSI (150PS, 1,498cc) — before ordering.
Q3: What is the VW/Skoda OEM part number for the IKER7A8EGS?
04E905602D — the part number used across Skoda and VW authorised dealership catalogues for the 1.0 TSI EA211 engine. Check for this reference on the packaging to confirm authenticity.
Q4: Does the IKER7A8EGS also fit the VW Taigun or Virtus 1.0 TSI?
Multiple authorised Indian parts retailers list it for the Taigun 1.0L and Virtus 1.0L under the same OEM cross-reference 04E905602D — which makes sense since the engine is identical. However, VW India owners should verify independently through a VW authorised service centre or the NGK India application chart. The same 3-plug rule applies — the 1.0 TSI is a 3-cylinder engine regardless of the badge.
Q5: What are the symptoms of a worn spark plug in a Skoda 1.0 TSI?
Rough or uneven idle, hesitation at low RPM before boost builds, increased turbo lag, hard cold starts, a drop in fuel efficiency, and an engine warning light with a misfire code (P0301–P0303). In a 3-cylinder engine, a misfiring plug affects one-third of total ignition work — the uneven idle and vibration are noticeable immediately.
