when should the stock plugs be changed?

 

When you start adding mods....

 

Depends on your mods. If you are stock, probably around 30-50K.

 

I would suggest you at least get under the hood and make sure all the stock plugs are in tight.

 

where is a good place to get them checked? would a dealer do it if i got the plugs from somewhere else? and what kinda plugs should i get? its a 99 and im not gonna do much just a chip and filter. maybe a couple other things.

 

TR6s or IT20s

So what i should i go for the TR6's or the IT20's???? I didnt know plugs were that expensive. Anybody know of anyone that has them cheaper???? My only mod so far is a new PSP intake.

 

all spark plugs have a "boost life". if you spend a lot of time in low boost 0-5psi, your stock plugs will last a long time. if you spend a lot of time in hi-boost (6-10) your plugs will last about 1/4 of that low boost time. the stock platinum plugs will last a very long time in low boost conditions. in hi boost the plugs are a "comsumable" and need your periodic attention, or something

 

NGK TR6 plugs are about $1.50-$1.75 each at most auto parts stores. Part Number 4177

 

Will i gain anything by changing to one of these high quality plugs???? The ones mentioned above? In other words is the money being spent worth it???

FlashSVT: are those the same as on the PSP website???? Why are they some damn expensive there then??(unless they include shipping at its all 8 for that price)

 

You will gain 'peace of mind' once you get over the trauma of changing them(if you do it yourself). You will know that you don't have any loose plugs after the change as well.

Listen to MRBBQMAN. He speaks the truth--about boost life--not too sure about some of the other things he has said . I changed mine at 18,000 miles and the platinum 'pad' under the ground electrode was worn away on most of the old plugs. I've been useing extra boost for 15,000 mile or so.

I got my NGKs from PSP and they were only about $20.00--for eight plugs.

Arigth thanks for the info of the PSP site i was starting to thin that 20 bucks per plug was a little expenxive. but 20 bucks for all 8 its notthat bad. Thats for responding
