yes you pull them after you take the bolt out that secures them to the head. sometimes a slight twist is necessary.

You can leave them in by all means there is no reason to chnage them. The cr10ek are giving people 2 hp more so you have to ask yourself if you want to spend the money or not.

Drove my Vector for 2 seaseons, have 5000 miles now, checked plugs and they still looked like new.
I put them back in & will run them again for this year. On my Expedition I change them every 200,000 km & have had no problems. Truck now has 403,000 km & only on third set from new. These are platinum plugs & 4 stroke. They are made to last.

Any problems with leaving them in to long and the threads seizing to the head? Something to think about?!

In most cases at the dealerships for cars and trucks the is a little known (to the public anyways) bulliten about the platinum spark plugs. becausr of the length of time between plug replacement it is recomended every 5-8000km service the plugs should at very least be wound out and threaded back in to avoid siezeing to the aluminum heads. Not following this practice could void you warranty if the dealership so chooses.

Been there done that with Caddilac

Iridium and Platinum tipped spark plugs are designed to operate under normal vehicle operating conditions for up to 100,000 miles (160,000 kilometers) without periodic maintenance. As stated in the owner's manual, maintenance needs may vary because of all the different ways people use their vehicles. As a result, more frequent inspections and replacements may be needed if the vehicle is operated in extreme conditions.

When no engine performance concerns are present, Iridium and Platinum tipped spark plugs should not be removed for periodic inspection and cleaning of threads, doing so may compromise the spark plug's ability to withstand their corrosive environment. The threaded area, although not sealed, serves as a protective environment against most harmful elements. Removing and cleaning spark plugs will introduce metallic debris and brush scrapings into the thread area which may further the corrosion process.

Chromate coated spark plugs should not be wire brushed or handled in any way once they are put in service. Chromium topcoats form a protective oxide on spark plugs that is not effective if scratched. Both coated and uncoated spark plugs will have the best chance of surviving a corrosive environment if they are left in position. Attempts to maintain spark plugs by removing them and cleaning the threads can actually create the corrosive condition that the procedure was intended to prevent.


This is a quote from a GM bulliten. Dealers are trying to sell more "maintenance " these days since there is good money in it.

Tell that to my customer that had to at his expense, replace a $1200 head and that was parts only at 102300km's

Why in the world would a head be warrantied at over 100,000km?
AND...why would you replace a head for a stripped out spark plug? I guess you have never seen a repair insert for aluminum heads (and I'm NOT talking about a heli-coil). I repair blown out spark plugs on fords wonderfull 5.4's about 6 times a year and never ever had one fail again. total cost to customer is 300.00 for plug, igntion coil, insert and labor. The dealer wants 3,000.00 to put on a new head on a f-150.

Oh yeah, that thing about removing plugs every 5-8000k is the funniest thing I have read today. LOL Eric

Caddi's and most GM products now carry a 160000km warrranty. I also have a guy that repairs things like that but he was un aware. The dealer told him and I have been told by two GM dealerships and one Chysler dealership that this should be common practice and if it's not recorded the dealership can refuse warranty.

Before you say that these guys cant be good customers, the guy with the Caddi buys new every year due to milage and every second for his wife. He is the owner of Upper Canada Corvette club and is flown every new modle year to Kentucky to watch his new Corvette being built right on the line.

Any type of lube to put on threads to stop seizing up?
