Spark plugs are a small part with a big impact on engine performance, fuel efficiency, and starting reliability. NGK has long been the default choice for Indian car owners. Brisk — a Czech manufacturer with genuine OEM credentials — is now actively available in India and raising a fair question: is it worth considering?
This comparison gives you what you need to make the right choice for your specific car.
Quick Answer
NGK has broader fitment coverage for Indian petrol engines, stronger distribution across India, and direct OEM supply relationships with Maruti Suzuki, Honda, Hyundai, Mahindra, and others. For most Indian car owners, it remains the lower-risk choice.
Brisk is a credible European manufacturer — one of the five largest spark plug makers in the world — with OEM supply credentials from Volkswagen, Audi, Škoda, and Volvo. Its iridium and silver electrode plugs are technically capable, but its fitment catalogue for Indian-market engines is smaller than NGK's, and physical retail availability is limited.
The short version: Match the plug to your engine's specification. Brand is secondary. If NGK has a verified part number for your engine, that's usually the simpler path. If Brisk lists a confirmed fitment for your engine and you're buying from an authorised channel, it's a legitimate option.
Brand Credentials: Who Are You Buying From?
NGK (Japan, est. 1936) is one of the world's largest spark plug manufacturers. In India, it supplies OEM plugs to Maruti Suzuki, Honda Cars, Mahindra, Renault-Nissan, and several two-wheeler manufacturers including Hero, TVS, Bajaj, and Royal Enfield. This OEM relationship means part numbers for common Indian engines are directly traceable and well-documented.
Brisk (Czech Republic, est. 1935) is a family-owned manufacturer and OEM supplier to VW, Audi, Škoda, Volvo, Seat, and Opel. It is the only manufacturer of silver electrode spark plugs in the world and an official supplier to KTM factory racing teams. Brisk has been present in the Indian market since the early 2020s.
Both are legitimate manufacturers. Neither is a budget or unproven brand.
Electrode Technology: What Actually Matters
Electrode material affects service life and voltage requirement — not raw "power." Neither brand will make a slow car faster.
| Electrode Type | NGK Option | Brisk Option | Typical Life (India) |
|---|---|---|---|
| Copper/Standard | BKR, DCPR series | Standard / Extra series | 20,000–30,000 km |
| Platinum | G-Power, Platinum | Platin series | 50,000–70,000 km |
| Iridium | Laser Iridium (iridium centre + platinum ground) | Premium Iridium / P35 (iridium centre + yttrium alloy ground) | 70,000–90,000 km |
| Silver | Not available | Silver Racing series | Performance use only |
Note on Brisk's differentiator: Brisk uses a yttrium alloy copper-core ground electrode in its iridium range rather than a platinum spot weld. Brisk's position is that this improves heat dissipation and reduces electrode wear. This is a genuine design difference — not a marketing claim — though whether it produces measurably better results in standard Indian driving is difficult to verify independently.
Note on Brisk Silver plugs: Silver is an excellent electrical conductor. These plugs are designed for performance, racing, and specific LPG applications. For a standard daily-use petrol car, silver plugs offer no meaningful advantage over iridium.

Fitment Coverage for Indian Cars: The Most Important Difference
This is where the practical gap is clearest.
NGK maps directly to popular Indian engines including the Maruti K10, K12, K12C, K12N, K15B, Hyundai Kappa and Gamma, Honda i-VTEC, Tata Revotron, and Mahindra petrol engines. Because NGK is an OEM supplier to several of these manufacturers, the cross-reference data is reliable and well-documented.
Brisk has a growing but more limited fitment catalogue for Indian-market engines. The P35 iridium, its most widely marketed plug in India, is compatible with many modern naturally aspirated MPFI petrol engines using long-reach, 16 mm hex iridium plugs — and Brisk India cross-references it against NGK ILZKR7B-11S for certain engine families. However, verified fitment data for specific Indian engine variants is less comprehensive than NGK's.
Important: Do not assume fitment based on thread size and reach alone. Heat range, gap specification, and electrode configuration must also match your engine's requirements. An incorrect heat range can cause pre-ignition, fouling, or accelerated electrode wear.
Availability and Counterfeit Risk in India
NGK is stocked by most automotive distributors, spare parts markets, and online retailers across India. If you need a plug urgently, NGK is almost certainly available nearby.
Brisk is primarily available through its official Indian website (brisksparkplug.com) and select authorised online channels. Physical availability at local parts shops and multi-brand stockists is significantly more limited.
Counterfeit risk is real for both brands. Fake iridium plugs priced ₹150–200 lower than genuine retail are almost certainly not genuine. Always buy from authorised dealers or verified retailers — not from unverified online sellers or roadside shops.

Common Mistakes to Avoid
- Buying by car name, not engine code. The Maruti Swift has had K10, K12, K12C, and K12N engines across different generations — each may require a different plug. Always specify the engine code and model year.
- Choosing by marketing claims. Both brands use performance language. The correct plug is the one that matches your manufacturer's specification.
- Ignoring heat range. Installing a plug with the wrong heat range — even if thread size and reach are correct — risks engine damage.
- Assuming iridium always means better. Iridium is correct when your engine specifies it or when you want extended service life. It will not improve performance on an engine specified for copper plugs.
How to Decide: NGK or Brisk?
Choose NGK when:
- Your engine has a verified NGK OEM or aftermarket part number
- You need quick availability at a local shop
- Your car is a common Indian-market model (Maruti, Hyundai, Tata, Honda, Mahindra petrol)
Consider Brisk when:
- You have confirmed the correct Brisk part number for your specific engine via their official catalogue
- You are sourcing from brisksparkplug.com or an authorised seller
- Your car is a European-origin vehicle where Brisk has OEM or cross-reference documentation
- You are running a modified engine, LPG setup, or performance application suited to Brisk's silver or multi-spark range
Conclusion
Both NGK and Brisk are credible manufacturers. For most Indian car owners driving Maruti Suzuki, Hyundai, Kia, Tata, or Honda petrol cars, NGK is the simpler and lower-risk choice — its fitment data is well-documented for Indian engines and genuine products are widely available.
Brisk is worth considering when fitment is confirmed for your specific engine and the product is sourced from an authorised channel. It is not a lesser brand — it is simply less established in the Indian market.
The plug that serves your engine best is the one correctly specified for it, genuinely manufactured, and installed at the right interval.

FAQs
Q1: Is NGK better than Brisk?
Neither is universally better. NGK has broader fitment coverage for common Indian engines and stronger retail distribution. Brisk is a credible European manufacturer with genuine iridium and silver electrode technology. The right choice depends on which brand has a verified part number for your specific engine.
Q2: How long do Brisk iridium spark plugs last in Indian conditions?
Brisk lists a 90,000 km life expectancy for the P35 iridium under standard conditions. In Indian city driving — stop-and-go traffic, heat, and variable fuel quality — real-world life may be shorter. Checking electrode condition around 60,000–70,000 km is advisable.
Q3: Can I replace an NGK plug with a Brisk plug?
Only if the Brisk plug matches your engine on thread size, reach, hex size, heat range, and gap specification. Do not substitute based on dimensions alone. Verify using Brisk's official fitment catalogue.
Q4: Is the Brisk P35 compatible with Hyundai and Kia engines?
Brisk India indicates P35 compatibility with certain modern naturally aspirated MPFI petrol engines in India. Fitment must be confirmed by checking your exact engine code and model year — not model name alone.
Q5: Are there counterfeit NGK and Brisk spark plugs in India?
Yes. Both brands have counterfeits in the Indian market. Purchase only from authorised dealers or verified retailers. Be cautious of prices significantly below the official retail price.
