[adam2562]

i have the slightest clue as to what a kind of spark plugs a N/A car should get... incase this helps.. my timign advanced and i have the usual lil stuff K&N drop in and TRD muffler .... thanks

i believe IK 20 are fine. (not IK22 [that's for s/c guys])

if not, then just stick to the platinum plugs.

[adam2562]

wuts the difference between ik20 and ik22... arents the 22's a colder spark? and the 20 is a hotter spark?

[Mole]

theoretically, yes.

why would it make a difference? i have no idea.

theoretically, yes.

A plug that operates at too high a temperature can also serve as an ignition source that actually starts the fire prior to the spark. This is pre-ignition, and it can lead to detonation.

Basically, a hot plug retains heat longer than a cold plug. Since turbo/nitrous/Supercharged engines are doing more work with more compression than stock, you need a colder plug (one that disappates heat faster).

Hope this helps.

thank you... so everyone likes their ik20's?

Seriously I understand the Sparkpulg talks, but same time no idea what brand you guys talking about.... I think I need some sleep haha

Denso is the company i use. they offer the IK20, IK22, etc.

Ah!! that spark info was most informative.

as for liking the spark plug, i believe people will say that they do feel an improvement of the new plugs, but in reality its just the lost power of the old plug that is regained back for optimal efficienc of the new plug.

you should be fine with OEM plugs but you could get IK20s if you feel like spending the extra money

[bassthrive]

Save the paper and go with the OEM PK20's

[DatSRBoi]

Is it true, I heard they have plugs that last over 100K miles even if abused?

[Mole]

^ they will last, but become more carbonated quicker.

thus cutting performance by not having as good of a contact.

I just had to change the plugs on my solara and I just used bosh plugs they were $1.99 each at pepboys, they are only single tip but I think something else is wrong with my ignition system on the new engine becuase all six of the plugs i pulled out were completely black, they were denso 20's. those back ones are a biatch to get the wrench on, especilaay if you have big hands and forearms. Taking off the strut tower brace helps a lot I also found it easier to do it from the drivers side and reach across.

I've hard that usage of Bosh on our cars reduces milage, I use Deno's i20's on all mine!
