Periodic replacement parts
On 2017-09-14 20:02:14
Since the car started knocking, I first exchanged it with a plug. Knocking disappeared, low-speed torque became thick. I am very satisfied.

It is the second order this time. After the previous replacement engine was torqueful and feeling was good, it is again order. This price is appreciated in iridium. I think that it is better if it becomes cheaper a little more with 4 sets or a set.

The price is also reasonable and the goods themselves are very satisfied.
Exchange by yourself

It is perfect for money and performance. As for life expectancy is not it?

We exchanged because it was 45000 km without exchange. Starting became easier as torque increased. If it is 100,000 km without this it is COSPA best! It is!

I bought a very old car so I bought it for fuel efficiency, starting improvement. As a feeling of use, idling seems to be stable. COSPA is also good.

If this is cheap Iridium! I want you to make it a little cheaper by selling sets such as 3 sets.

For iridium plug, it is inexpensive and it is a very good commodity. Tone is good without problems after use.

It can be used normally. I would appreciate it if it was a bit cheaper.
During machine maintenance

Mini car with mileage of 80,000 kilometers During normal idling, I felt Power Dow, so I replaced it with a cheap champion spark plug, I was able to feel the power as much as I depressed the accelerator, very satisfied doing.
Replace the plug

I am using it for Honda beat. It is handy because it is a difficult car to exchange.
Since it was time to replace the car, I replaced the coil and plug at the same time
On 2016-12-13 18:17:04
I am satisfied Because it is a spark plug, there is no improvement point.

I was worried about the quality aspect compared with DENSO and NGK, but it was a good product without any problems.
For BMW plug replacement
On 2016-12-01 18:17:16
For old BMW replacement. Since genuine products are difficult to obtain on a 2-pole plug and expensive, purchase after confirming compliance. Since I have not installed it yet, I do not know, for example, fuel economy, but startability has certainly improved.

The price is cheap and saved. The sensation I used is a product that I can not understand, so I will watch it and watch it in the future.

I do not ask for a good reputation on the streets, but I trust it with my favorite manufacturer. Although it is related to a product warranty of 100,000 kiloliters, we will make a replacement at 40,000 kilometers, because the light usual revolution is about twice the size of a regular car.

Previously, I felt that Iridium definitely lasted long, but I feel that the difference has decreased in recent years.
On 2016-08-27 23:14:27
It can be purchased at a cheap price and operation is no problem.

Mitsubishi ek Wagon (H82W) Traveling environment - It is a region with many gradients (around 8 to 10%). With the normal plug, if the speed dropped sharply during the ascending slope and the following car, there was a fear of a rear end, so we exchanged for this product. The average fuel consumption fell from 15 km / L to 13 km / L, but the initial problem "speed reduction during climbing" was improved. I thought about trying other manufacturer's products, but it was good that I decided on a single shot. It is about time to replace so it is a repeat purchase.
