These plugs are working as expected.

Its a Motorcraft product and I only use Motorcraft plugs in my Fords,2.

Now it is listed on another website to fit so Im not sure what the deal is, but it did not work for my application, I instead had to use the copper version of the plug (SP-450) which is no problem, just have to change them out more often, Just a buyer beware, may want to pull a plug and see whats in the vehicle first.

I drive the Sierra and Cascades a lot, with a bunch of full throttle hill climbs at altitude in all kinds of weather - the engine does not ping with these plugs and decent gasoline / correct timing.I will change these out again about 35k to 40k miles from now if I still have the truck, which is much less than their service life, because I want to keep track of engine condition and avoid stuck or loose plugs.

Van in which plugs are installed in runs better with these new plugs.

Jane's Review: Should I buy this product?

Jane's Review

Yes! I highly recommend this automotive replacement spark plug based on its brand popularity and manufacturer ratings. Let's go over the reasons why buying this automotive replacement spark plug now is a good idea, and also things to consider before you decide on this item.

1. Motorcraft is a known automotive replacement spark plug brand

Motorcraft doesn't attract too many people on Amazon among other automotive replacement spark plug brands. But I found some YouTube videos that talk about this product, which means this is a widely known product/brand. I have attached the videos above and links in the additional research section down below, so don't forget to watch and read those!

One thing to be careful about here is that I'm not verifying if this product's maker is a household name or not. This section is more focused on whether this is proven enough by its consumers, whether people actually love this product.

2. Manufacturer has very positive reviews on all their products!

The maker of a product is another factor you want to definitely consider before you buy anything. What if there is a piece missing or there is some defect in the product? With anything you buy online, there is a small chance of this happening. But don't worry too much, because Amazon has an amazing 30-day refund policy (Amazon❤️). Still, you want to make sure that the manufacturer or the seller has been helpful in resolving this kind of problem and/or has been helpful to its customers about general product inquiries. As you see in my manufacturer report below, Motorcraft has very positive reviews for their products. It's generally a good sign if the manufacturer has good reviews overall. If your purchase decision heavily involves how well they make their products and treat their customers, this is likely a safe bet.

3. This automotive replacement spark plug has positive reviews on the internet

Some people have a great experience with a product, while some are unlucky and get a defected item and have to go through the whole process of returning them. Since people have different experiences about a product due to various reasons, don't read too much into one good or bad review. Reading multiple reviews with different ratings can help you picture how good/bad the product generally is.

This automotive replacement spark plug has positivereviews on the internet, and based on current trends, it's likely that people will like this automotive replacement spark plug more a week later. I summarized what fans and haters say about this product above in the good/ok/bad table, so don't forget to read those since they paint the whole picture! And of course, if you want to read more detailed reviews, many of them are on Amazon!See More Reviews on AmazonSee More Reviews on Amazon

4. The price might go up, so buy now if you need this!

Price is one of the most important factors in making a purchase decision. I analyzed the price of this product in four parts: its recent price change, when it was most expensive/cheapest, its price volatility, and a price prediction I made, just in case you want to wait.

First off, let's talk about its recent price change. The price of this product has gone up, resulting in a 2.33% price increase.

Next, we need to look at its highest price and lowest price. Historically, the highest price point for this automotive replacement spark plug was $3.95, and the lowest price point was $2.51. The current price is nearly the highest it has ever been. If the best price is what you're after, now isn't exactly a good time to buy this automotive replacement spark plug.

What about its availability and price volatility? This is another aspect we have to dig into before buying something. I haven't seen this product being unavailable since I started reviewing this product. So as far as the availability goes, this product is solid. If you plan to make a repeat purchase of this kind of item, this is your product! In addition, I've seen a small amount of price movement with this product. From what I've seen, the price is likely to move up or down by an average of 2.05% at a time.

Considering all this, will the price go up or down in a week? Based on past price points, I expect the price to be $3.82 a week from now. It might be best to purchase as soon as possible before the price becomes too high.
