Forced Induction Best spark plug

Best spark plug

What is the best spark plug out there for the Corollas? The car comes with iridium plugs IK16, can the IK20 from the 2ZZ-GE engine be used?

it won't make any difference really. the ECU setup is designed to work with the OEM plugs but if you have it accelerated or (advanced) you can use the Laser iridium but it only provides a better spark and more complete fuel combustion.

So I could get ether one the IK16 or the Ik20 for a 2002 Corolla? The IK16 is a dolla cheaper than the IK20.

yes and no. the reason being is that the ik16 is different suited compression ratio to that of the 1k20. since the compression ratio is higher on the 2zz it needs a hotter spark. you can possibly use the 1k20 on the 1zz but you have to make sure that its length is no longer than that of the ik16. But since you have a turbo you might need that "extra heat" since it runs for a higher temperature. i have the OEM spec spark plug but in the laser iridium form so its better suited for the car overall. but the price varies.

I'm a huge fan of the Baush Platinum +4 spark plugs. I've definetly been able to feel a difference driving with them since I've had them in and the same applies to any one I know that has them.

How do i say this. This sparkplug was designed only to get better gas mileage and have even spark for vehicles that have an irrregular intake and exhaust design such as a SOHC engine. In Reality you don't really get more power from them. If you notice the center electrode is very big when compared to an iridium plug. if you're looking for more power you need a smaller electrode for a hotter spark. even though it has four ground power sources it can't compensate the amount of power going to it and it does not make a notable difference if you have a tuned intake such as ours, plus our engine is a DOHC so the only difference you will get between the iridium and the Bosch Platinum Four is gas milage and low speeds.

if you have an older model Rolla like a 93-97 or below you will notice a more broader power band overall. because the intake is a single plenum design, not tuned.

The prices are from the local Advance Auto Parts.
Bosch Platinum 4 ,4.98 each
NGK Laser Iridium , 8.98 each.
what i have described is excatly what they told me as well.

isn't the 1k20 for the 2zz colder than the ik16? I am running ik20 plugs for the turbo.

Yes, IK20s are colder than IK16. I installed IK20s as part of my pre-n2o stuff..

I think that the IK16 and the IK20 are the same lenght, here are the details
IK 16 http://www.densoproducts.com/resultsSearch.asp?s=9&txtPartNumber=IK16
IK 20 http://www.densoproducts.com/resultsSearch.asp?s=9&txtPartNumber=IK20
I think I will go with the IK20 since my car is turbo.

Both plugs are the same size..definitely go with IK20 since you're turbocharged.

IK20 less spark works better for TURBO.
IK16 has a hotter spark works well for NORMALLY ASPIRATED ENGINES.
In my case i can't use the IK20 because it does not allow for enough spark and since it runs on a non-turbo and non-nos setup its okay for me. if you have a turbo Cadet Lee is right i spoke to my friend and he said the IK20 works best for turboed engines since with a IK16 it may cause over detination.he works for the local Toyota(s) dealer, he is one of the master techs. So i follow his work.its your choice to decide if you want to use it.

i stick with denso plugs which is basically oem.

I just take a cork off the top of a whine bottle and push a nail though it and mash the wire on. Works real good. I should do a DIY.

hehehe the ghetto but innovative way!

Do I have to drink the whine first or after?

I still have my IK20s installed..don't want to pay the $$ for hotter plugs. It still runs, but I have a higher chance of fouling the (IK20) plugs faster than hotter plugs would.

i have to replace my plugs every 5K miles and they are IK16. i tried the IK20 and the car for some reason did not feel the same,It actually felt a bit sluggish but not really noticable. So i just gave them to my friend and purchased the IK16, You also run with NOS so i guess they work better for your car.I learned my lesson so i will stay away from high shots of NOS.

i think you have to drink a bit first then drink during the process and finish after. Wine ain't the best tasteing but its okay.

I've had some really nasty wine..and also some that wasn't too bad. Depends on what you get, I guess.

Heh..we're really getting OT here

nasty wine really aged dry wines...
I love Nora... dry but fruity
and basically any fruity wine... preferably white... red wines are mostly ok though, and young wines...
I'm gonna drink a 100 y/o wine if I can in 2048... wish me luck to get that age...
and that it tastes fucking good @_@...
it was given to my boss by a friend...

the story of the character is that he was so good at sampling, that he was taken to japan and paid like 150K JUST TO TASTE A WINE AND GUESS EXACTLY were it was made... in the world... and the year

hey its how to forget the pain if you do something stupid while installing/removing the spark plugs.

I know but lol...

i use some bosch platinum +4 that i stole from work..feels like the same old stuff to me when i had oem densos

don't ever say you stole. just say you borrowed, hehe. the platinum 4 is mainly to get a better spark and a bit better combustion.

**** n00bie, I usually don't jump peoples *** but ****. I already read two posts today from you and one is "I stole stuff from work" and the other is "My bootlegged copy of XP" what is the deal man? If you want to be a crook that is one thing, but don't advertise it so much, jesus.

the heatrange of a plug isn't the 'heat' of the spark. it is the plugs ability to retain and/or dissipate heat as a whole. you want colder plugs in forced induction so they dissipate the most heat, and keep the temps of the combustion chamber that much colder. otherwise you run the risk of detonation (ie, a 'hot spot' on the plug after a short period)

the +4's are garbage for most imports. i sell them to domestic owners who want plugs that will last longer. also, platinum doesn't conduct electricity as well as copper... so, a regular v-power ngk plug will perform better (until it fouls) than a platinum, double platinum, splitfire platinum, +2 or +4.

forgot to mention.... platinum plugs in a forced induction car are an even worse idea. the platinum on the plugs is brittle (hence why auto parts store guys SHOULD tell you to be careful when gapping a platinum plug... you can break/crack the platinum)... forced induction motors are known for chipping the platinum off the plugs.... then you end up with small hard pieces of metal floating in your engine unless you're lucky to have it pass through the motor w/o problems
