5 best spark plugs for Chevy Cruze 1.4 turbo- Reviewed

All the products mentioned here are available online on amazon.com.

1. Bosch Automotive 9603 Double Iridium OE Replacement Spark Plug

Product details:

1. Double Iridium firing pin
2. 0.6mm fine wire firing pin
3. 360 Degree continuous laser weld

Before I bought these spark plugs, I did a lot of research on them. This brand and this plug come highly recommended by me. I received exactly what I ordered in the form of plugs. They were a perfect fit for my Chevy Cruze 1.4 turbo with a lot of miles on them. 

They were properly pre-gapped, and all four plugs in my shipment had the same gap and good quality control. There were no concerns. I saw an immediate improvement in fuel economy. Approximately 15% to 20%. 

That’s not a lot of money, but it shows that they’re an improvement over my previous, worn-out plugs. The older ones are a different brand, but they are single-iridium. I believe the old plugs have between 40k and 60k miles on them. 

That is, just one of the two electrodes is made of long-lasting iridium. I’m not sure if the other electrode on the plug is copper. However, the old ones are clearly worn, and the bottom electrode is virtually gone.

The new Bosch-9600 plugs have iridium on both electrodes, making the spark/arcing surface of the electrode extremely robust. I expect these to last at least 60k miles. Which may be more than my automobile can handle.

2. ACDelco GM Original Equipment 41-121 Iridium Spark Plug

Product details:

1. Core Material: Iridium
2. Top Material Type: Nickel
3. Vehicle Service Type: Motorcycle

I had roughly 90,000 miles on my 2014 Cruze absolute new model and decided it was time to change the plugs. I’ve come across some contradicting information about which plugs to get for this car. Because the original plug was a Delco 41-121, 

I chose to use the same plugs. These fit nicely and were torqued to 18 ft-lbs with no problems. They are also pre-gapped for the Cruze engine. Very simple to install; just be careful not to over-torque and you’ll be OK. 

The spark plugs were a great bargain, and the shipping was quick as well. I put these in my car and they worked perfectly. These are unquestionably the best for GM automobiles. And the pricing is also unbeatable. 

They’re the only ones I use in our 2014 Cruze. Purchase these and do it correctly the first time. One thing to bear in mind is that you will need to purchase each of them. If you order one, it will come in its own box. If you order four, you will receive a larger package. 

Because many cars have four cylinders, it is typical to replace them all at once. These spark plugs are expected to last between 75000 and 100,000 kilometers.

3. Autolite AP3923 Platinum Spark Plug

Product details:

1. Core Material: Platinum
2. Top Material Type: Nickel, Alloy Steel
3. Full platinum tip

For the price, this is a good standard platinum plug. I’ve been running them for 3000 miles. The Iridium plug was replaced. There is no reduction in performance or gas mileage. It’s also less expensive. I’ve been using these plugs in my Cruz for at least 20 years. 

Excellent high mileage plug. If you can’t or don’t want to spend the money on iridium, these are, in my opinion, the next best bet. I don’t recall ever purchasing a plug for less than a dollar, and it’s the recommended replacement for the factory plug, which costs $20.

The only drawback is that on the spark side of the plug, there is no covering. This means that as the plugs are moved around during shipping/delivery, the contact point may become closer to the other contact, causing the gap to change. 

This is why more conscientious manufacturers include a sleeve at the end of their plugs. If you drop the entire box, it will land on the contact side, causing all of your gaps to be incorrect.

4. Autolite 3922 Copper Resistor Spark Plug

Product details:

1. Brand: Autolite
2. Core Material: Copper
3. Top Material Type: Alloy Steel

Perfect replacement spark plugs for a 2014 Chevy Cruz, installed without a hitch. I noticed an immediate change in my engine after installing these plugs, and I also improved my mileage, so I removed the NKG and replaced it with the Autolite.

These spark plugs contain an iridium-enhanced center electrode and a nickel-plated shell to provide increased life and a more concentrated ignition for improved overall ignitability and performance.

So far, everything is going well. I replaced my plugs after 100,000 miles. I’ve seen higher power and somewhat better gas mileage. It’s actually quite simple to change and gap spark plugs on your own. 

This is a perfect fit for a 1.4 Turbo Chevy, and I got it for my car but only used it for three days before my son’s spark plugs failed him. So he had to put these in his car. No issues with plugs and fit great.

5. Denso (5310) IK22 Iridium Power Spark Plug

Product details:

1. 0.4 mm iridium centre electrode
2. 360-degree laser welding
3. U-groove and taper cut ground electrode

It works perfectly. I couldn’t detect a difference when new against NGK 2667 BKR7EIX, but at approximately 15,000 miles, my MPG’s have grown significantly worse. I observed a difference after 20,000 miles using NGKs. 

It would be fantastic if NGK provided these in their Twin-Tip configuration with the necessary spacing. At 130K miles, I replaced the OEM plugs on a 2011 Chevy Cruze with these. The gap on previous plugs had degraded significantly. Expect these plugs to last longer than the originals.

My Chevy Cruze Fit was misfiring, and the plugs were on their way out. I chose these over the recommended ones since they are a bit colder on the firing range, which actually helped my acceleration. 

One of the six was gapped differently than the others, so I set the gap to factory specs (more than what they came with, because the truck’s ignition system is highly robust and can withstand an increase in the gap, and they came gapped about 0.025″, so I set them to 0.043″.
