Boys and gals (gotta be gender sensitive)

Time to invest in new plugs, manual says for 3.2:

Denso
PK16PR-L11 Platinum $2.60

NGK
PFR5L-11 Platinum $2.00

I have been checking AdvanceAuto and they also recommend Iridiums. Should I stay with Platinums?

Or Iridiums starting at $9.00? Double Platinums are $ 7.00.

I tend to use OEM Platinums and they are good again for 100K.

 

AdvanceAuto is running the $10 off $25, time to go shopping again!

 

NGK is as to stock as you can get.

I replaced my spark plugs the other day and it took me about 15 minutes to do everything.

Very easy to change them out on our cars.

 

As I have read from countless posts, NGK is friendlier to our TL's than Denso. Will do the Platinums, NGK.

 

link?

and i go iridiums...

 

Here ya go!

Have at it! All legit. Save as a jpg and print nicely. I am going shopping!

 

i got my iridiums for 3.99 a piece . 9.00 is kind of alot

 

Where did you get your NGK Iridium?

 

got them at schucks . i just looked it up online and it said 6.99 but i have my receipt right here that says 3.99

 

I recommend NGK iridiums over platinums.

 

Iridiums it is.

 

remember to gap them . i almost forgot to gap mines last time ....

 

They do come in pre-gapped @ 0.44 right?

 

Have not purchased plugs which were not pre-gapped in recent history. a=As long as when you buy it it is specifcially stated to match your car.

 

yes they come .044 gapped . 3.2tl and 2.5tl manual says .043 . dont know if it would really matter but i do it anyways

 

Did you adjust your new plugs prior to installation?

 

Since the plugs are scheduled for replacement @ 105k miles, have another 10k to burn. So much for what plugs to use...

 

As well as the timing belt and water pump, all @ 105k.

 

yes i adjusted the spark plugs wit the spark plug gap gauge before installation

 

go with ngk iridium helps a little bit more with gas

 

spark plugs help with gas ? i never knew that ..

 

^ Yes, a cleaner burn means less wasted.

~Cheers~

 

After I replaced mine I saw the mileage on my car go from 175 per tank to like 200-210ish.

 

I believe it.

 

Iridiums are a better built spark plug, hence the extra cost. I run Iridiums in my other 2 cars and they perform well. I hate the cost! I would buy a couple boxes if they were $3.99 each.

Just a few facts from Wikipedia about Iridium:
The global demand for iridium in 2007 was 119,000 troy ounces (3,700 kg), out of which 25,000 ozt (780 kg) were used for electrical applications such as spark plugs; Although it is one of the rarest elements in the Earth's crust, with annual production and consumption of only three tonnes, it has a number of specialized industrial and scientific applications. Iridium is employed when high corrosion resistance at high temperatures is needed, as in spark plugs, crucibles for recrystallization of semiconductors at high temperatures, electrodes for the production of chlorine in the chloralkali process, and radioisotope thermoelectric generators used in unmanned spacecraft. Iridium compounds also find applications as catalysts for the production of acetic acid. In the automotive industry, iridium is used in high-end after-market sparkplugs as the center electrode, replacing more commonly used metals. The claimed benefits are greater economy and improved acceleration.

 

I was wondering wat kind of spark plug Im using cuz i forgot...
So I took them out and holy shiet ... spark plugs covered with oil and the oil looked really dark...
I changed the valve cover gasket about 1 year and half ago...
So what are other chances causing this?

Thank you

BTW, I have NGK iridium

 

Bad o-rings or valve guides.

 

Thanks, Mike...
