Spark plugs

[efedor]

I just changed the spark plugs on my 04 Boxster and found out that Porshe recommends you change the every 60,000 miles. My boxster has 25k and I felt that with gas prices so high changing the spark plugs wouldnt hurt, Do you guys think I should of waited or do you feel I did the right thing? I put the NGK laser(10dls each)spark plugs in myself..any opinions?

at almost 4 yrs old..... which in "most" car's lifetime = 60K.... not a bad move especially if they were fouled.

Any reason you didn't use an OEM plug??

After a 20 years driving many fast cars i think that if you dont have a serious monay problem and you like to spend a few $ is not bad to

change the spark plugs more often than the maintainance says the car accelerate better with new sparks just be carefoul not to use sparks wich can make hole to the piston. few years ago there are a double lens spark plugs wich make a lot of trouble. generally bosch sparks with the four 4 lens are very good.

Something that i know for sure, it is very good for the car is to change Valvolines in the gear box and transmission oils more often than 100000km porshe or bmw or mercedes says. these oils many times contain a lot of metal dust.

the only bad for an engine think is to change engine oil very soon because the oil need some time to make a cover foil inside the engine and protect the parts.

spark plugs you can change every week :)) the ingition is the best with new ones and the consumption is lower. Platin plugs are the safest because there is no way of braking a lens and fault in the cylinder piston

Update

I took the car for a test drive after I installed the NGL IRIDIUM spark plugs and I could tell the difference, When I woke up this morning to go to work at 33f weather everything was well UNTIL I came to a stop, The idle began to get rough and dropped to the point I had to accelerate it so It wouldnt die. I drove away and it worked very good then on my way back home once in a while It began to get rough as I accelerated, It didnt do it all the time but Im worried, should I double check my work to make sure I didnt leave a spark plug loose? should I use THREAD LOCK on the spark plugs? Or should I simply take the ngk's out and put the original ones back and order the OEM spark plugs?? Please help me out. Thansk

i told before you have to use only recomended spark plugs to avoid a huge brake or hole on the piston

the spark plugs you used are recomended?

many aftermarket spark plugs can make the car accelerate better than the recomended but many times make problems like (idle rpm drop and the engine is close to stop when you depress the accelerator pedal quickly) (more consumption) (not good gas analizer resaults) etc

the plugs you install was like the old ones? with 1,2 ,4 ignition pins?

of course wires and coils is not so easy job to fit well as the old cars with just one rubber pipe where you have just to listen the "click" to fit

NOPE the NGK'S have only one prong insted of 4 like the stocks, they have the pin made of iradium and the loop part made of platnium. They can be made out of gold but if they make my baby run like crap I dont want them. Why did I buy them? Because I was told by the auto parts store that they are the best for that car :( I will replace them with the old ones and order the OEM"s any suggestions of a web page that sells them for a good price? thanks

.....should I use THREAD LOCK on the spark plugs? .....

I remember reading in this forum that nothing should be used on the threads; you might want to search on that topic. --Brian
