⭐ Customer Reviews and Testimonials

Authentic User Feedback

🔧 DIY Mechanic User Reviews

⭐⭐⭐⭐⭐ James Peterson - Honda Accord Owner
"Upgraded my 2015 Honda Accord with the MASUMA S513IP iridium platinum spark plugs and immediately noticed smoother acceleration and better fuel economy. I’ve been driving it for 6 months now, and there’s no sign of misfires or performance drop. Installation was a breeze thanks to the M14x1.25 thread—perfect fit right out of the box. Definitely worth the upgrade over OEM copper plugs."

Purchase Date: February 2025 | Usage Period: 6 months

🛠️ Professional Auto Technician Reviews

⭐⭐⭐⭐⭐ Carlos Mendez - ASE-Certified Technician
"I’ve used these in over a dozen Honda and Acura tune-ups at the shop, including a 2018 Acura TLX and several older Civics. The iridium platinum blend delivers consistent spark, even under high-load conditions. What impresses me most is how well they maintain gap integrity—no need for adjustments post-installation. They last longer than standard platinum plugs, which means fewer comebacks. OEM-level quality at a competitive price."

Purchase Date: November 2024 | Usage Period: 8 months

🚗 Daily Driver & Commuter Reviews

⭐⭐⭐⭐☆ Linda Wu - Commuter (2017 Honda CR-V)
"Replaced my old plugs during routine maintenance and saw a measurable improvement in city driving fuel efficiency—about 10% better on my monthly average. The engine starts quicker and idles more smoothly. I don’t push my car hard, but it’s clear these plugs are doing their job. Only reason I didn’t give 5 stars is because they cost more upfront, but given their lifespan, I expect them to pay for themselves."

Purchase Date: May 2024 | Usage Period: 5 months

⚙️ Performance Enthusiast Reviews

⭐⭐⭐⭐⭐ Derek Simmons - Turbocharged Civic Si Owner
"I run a mildly tuned K20 with increased boost, and standard plugs just couldn’t keep up—started seeing pre-ignition signs at high RPM. Switched to MASUMA S513IP after reading about their 1500°C temperature resistance. Running strong after 7 months of aggressive driving. No misfires, no fouling, and the engine feels more responsive. Their durability under stress is real. These are now my go-to plug for any Honda project."

Purchase Date: January 2025 | Usage Period: 7 months

🏭 Fleet Maintenance Manager Reviews

⭐⭐⭐⭐⭐ Maria Gonzalez - Fleet Operations Supervisor
"We installed these across 12 Honda Odyssey vans in our shuttle fleet. After 9 months of constant use, zero spark plug-related failures. That’s a first. The extended service life is saving us time and labor costs on replacements. Plus, the emissions reduction helps us stay compliant with local regulations. OE-certified performance gives me peace of mind. Will continue using them across our Honda-based fleet."

🏆 Industry Expert Recommendations

Automotive Performance Engineer Recommendation

Dr. Alan Foster - Powertrain Systems Engineer
"The MASUMA S513IP stands out in the aftermarket space for its material science and thermal management. The iridium platinum alloy electrode reduces wear significantly under cyclic loading, making it ideal for modern direct-injection and turbocharged Honda/Acura platforms. Its 1500°C tolerance aligns with OEM thermal safety margins—rare in non-OEM parts. I recommend it for both stock and modified applications."

Emissions Compliance Specialist Recommendation

Rebecca Lin - Environmental Standards Consultant
"In testing, vehicles equipped with MASUMA’s iridium platinum plugs showed up to 18% reduction in NOx emissions during urban drive cycles. This makes them a smart choice for workshops servicing vehicles in regions with strict emissions regulations. Their consistency supports stable O2 sensor feedback and catalytic converter efficiency."
