Autolite Iridium XP Automotive Replacement Spark Plugs, XP6203 (4 Pack)

These worked great for my car. Swapped out the old plugs and the engine started running smoother right away. Acceleration feels better and the idle is nice and steady now. Super easy install and they seem really well made. For the price it's a no brainer if you want to do some quick maintenance yourself. I'd definitely buy them again next time I need a tune up.

Good price,good quality, and perfect fit for a 1.6l kia soul

Spark plugs bought for 2013 Kia Soul. Parts fit and have had no issues for months. Great price for them. The same brand was triple the price at O'Reillys

👌 👌 👌

My car eats a set of spark plugs every 30k miles. I’ve tried all the expensive brands hoping to find some that last longer, these seems to perform just as well and last just as long as those top tier brands.

I recently purchased the Autolite Iridium XP Automotive Replacement Spark Plugs, specifically the XP6203 model in a convenient 4-pack, and I must say that they have delivered reliable performance for my vehicle. First and foremost, the build quality of these spark plugs is impressive. The iridium construction ensures durability and longevity, allowing the plugs to withstand the demanding conditions under the hood of my vehicle. I appreciate the peace of mind that comes with knowing I have high-quality spark plugs installed. Installation was a breeze, and the spark plugs fit perfectly in my engine. The precise engineering of these plugs ensures a proper fit, allowing for optimal performance and efficient combustion. I experienced no issues with misfires or compatibility, and the plugs integrated seamlessly into my vehicle's ignition system. In terms of performance, the Autolite Iridium XP spark plugs have met my expectations. They provide a reliable spark, ensuring smooth engine starts and consistent ignition throughout my driving experience. I noticed improved throttle response and acceleration, resulting in a more enjoyable and responsive driving experience. Furthermore, the iridium tips of these spark plugs contribute to their longevity. They offer excellent wear resistance, minimizing electrode erosion and extending the lifespan of the plugs. I appreciate the fact that I won't have to worry about frequent replacements or decreased performance due to worn-out spark plugs. However, I would like to mention that while the Autolite Iridium XP spark plugs perform well, they may not necessarily provide a significant boost in performance compared to standard spark plugs. While I did notice improvements in throttle response and acceleration, the difference may not be as noticeable for all vehicles and driving conditions. In conclusion, the Autolite Iridium XP Automotive Replacement Spark Plugs, specifically the XP6203 model, offer reliable performance and durability for your vehicle. The high-quality construction, ease of installation, and improved throttle response make them a worthy investment. While they may not provide a dramatic performance boost for all vehicles, they are still a reliable choice for maintaining optimal ignition and engine performance. I would recommend these spark plugs to fellow car enthusiasts who are looking for reliable replacements for their worn-out plugs.

People seem to say autolite are not as good but I can't really narrow down why some people think they're lower quality. Do they not spark as well, are they cheaper material? Apart from few negative reviews where they say the spark plugs failed (which tends to be present with all products), it's hard to narrow down why these are inferior. This is the second set I've bought (first was for a different vehicle) and they have been working fine with the first set been fine for over a year so far on my other car. I'm going to be replacing the spark plugs around 40,000 anyways especially with this cheaper price, so I'm not worried. Maybe they wear out after 100,000 miles instead of 150,000 like the "better" brands but I won't be using them that long.

2013 Hyundai Accent. Originals has 120K on them and they were due.

Solo recibí una pieza de 4 pedidas. Devolver la pieza y esperar hasta que el banco reembolse y ya no pude dar el servicio a mi auto. Molesto!!

I picked up these Iridium Spark Plugs after noticing my car was becoming sluggish, less responsive, and not as fuel-efficient as usual. When I checked the old plugs, I found some oil buildup, which confirmed it was definitely time for a replacement. After installing these, the improvement was immediate. The engine runs much smoother, acceleration feels more responsive, and overall performance has noticeably improved. I’ve also seen better fuel efficiency compared to before. These iridium spark plugs feel like a high-quality upgrade—durable, efficient, and built to last longer than standard plugs. Installation was straightforward, and they’ve been working reliably since. Overall, if your vehicle is experiencing rough performance or decreased fuel economy, this is a solid replacement option that delivers real results.

2012 Hyundia Sonata: cheaper than Denso iridium. Will see how well they last in Cdn winter. So far being new, good fuel economy 👍🏻

The spark plugs came in a box a 4 for convenience. I checked the gap with a wire guage and adjusted them for my engine. The engine had been knocking earlier and with the new plugs installed, the knocking went away. Good product 👍

The price was right and they work as expected, right gap, no issues. I only gave them 4* because I compared them though with the DENSO I had (and kept for 100K KM) and they are rougher made than those.
