What’s the big deal about platinum tipped spark plugs?
Now I know what you may be asking. “Vince, a spark plug is a spark plug…” “There isn’t a lot to know about spark plugs, eh?”
Wrong. As it turns out, spark plugs are not just small pieces of copper and metal infused in a thermally efficient package. Spark plugs have evolved to cope with modern engines equipped with the latest advancements such as turbocharging and direct injection technology. Gone are the days of carburetors and fuel guzzling engines (well, for the most part) and copper spark plugs.
Most newer vehicles now days are going to utilize “Platinum” spark plugs. Check out this writeup that Matt did: Choosing the right spark plugs for your vehicle
In this review of the Denso Platinum Spark Plug, I wanted to find out if upgrading to a set of platinum spark plugs is worth the extra cost. I was also curious to find out if the Denso PK200TT will have any positive effects on the performance and fuel economy of my daily driver. So let’s get into it!
- Twin-tip technology with 11 mm platinum center electrode and 11 mm titanium enhanced ground electrode
- Improve fuel economy, better acceleration and faster starts than all other single platinum plugs
- Purified alumina powder insulator provides exceptional dielectric strength and thermal conductivity, allowing the material to stand up to extreme stress
Features of the Denso PK200TT Platinum Spark Plug
I purposely allotted the first part of this Denso PK200TT Platinum review to discuss the stand-out features of this spark plug.
The ‘TT’ stands for Twin-Tip. This spark plug is equipped with a platinum center electrode and a titanium-enhanced alloy ground electrode tip. The design stems from Denso’s Super Ignition Pug Technology which was meant to engineer a new breed of spark plugs for the most advanced vehicles in the market. Think Bentley, Rolls Royce, and Cadillac…
But now, this twin-tip technology can be yours in the Denso TT Series, and you don’t need to shell out big money to buy a set for your humble compact or midsized sedan. Come to think about it, the Denso PK200TT Platinum spark Plug costs around [see lowest price], and can last you up to 100,000 miles.
Using platinum alloy on the center electrode allows the tip size to maintain a diameter of 1.1 mm to enhance the service life of the spark plug. The titanium alloy on the ground electrode is engineered to further enhance the durability of the spark plug. The titanium-infused electrode will also help to minimize erosion on the tip to maintain a larger spark even after tens of thousands of miles. This technology will also reduce emissions so you can minimize the carbon footprint of your vehicle.
Test Drive and Review – Toyota Camry
My 2004 Toyota Camry LE with the 2.4-liter four-banger was due for servicing. This is the perfect opportunity for me to test the Denso platinums. After changing the oil and the oil filter, I took the liberty to replace the air filter for good measure. The old spark plugs were replaced and my test was on the way.
When everything was set, I started the car and drove it around town to see if I can discern any difference.
It would be foolish to expect mind-blowing results from changing to new of spark plugs, but I did notice a slight improvement in acceleration. I also noticed that the engine was idling a bit more silently than usual. It must also have something to do with the fresh batch of fully-synthetic oil circulating inside the engine. Upgrading to the Denso spark plugs managed to improve the throttle response. I also noticed better fuel mileage on the highway, which is always a nice thing.
A 2 MPG fuel increase….
Before the spark plug change I was getting about 20 MPG in town and 30 on the highway.
After swapping out the tired old factory spark plugs for the platinum plugs, my MPG went up to 21/32. Not the biggest improvement, but I’ll take any fuel savings I can with the price of gasoline these days!
