Engine spark plugs

spark plugs

hi everyone,

i just recently installed the NGK IX iridium spark plugs and when i pull the old one out i found that the stock plugs are NGK regular iridium plugs.

the question: how come the manufacture said that the plugs is suppose to be Denso iridium and it turns out that they are using NGKs?

just wondering :?:

My 2004 CE 5 spd was assembled in Canada and came with regular Denso iridium plugs... How do you like your NGK IX's? Did you notice any improvement?

check out my cardomain

hey check out the comments i put on my page.

i feel a lil different more clean accelaration. i like it. is also cheaper than denso plugs

I think they come from the same company but I could be wrong on that one.

Any gains or losses from the switch :?:

NGK and Denso are not the same company. However, they do make interchangeable parts. Some Toyotas come with Denso plugs, some with NGK, and some with both (yes you are reading right). Some 2nd gen camrys with the 2VZ-FE 2.5L V6 came with NGK plugs in the rear bank and Denso in the front bank.

weird

i got some good feel out of the IX plugs. feels a lil gain not much but it response better.

funky stuff with the plugs. hehe thats car dealer/manufacture for you try to save money. NGK plugs 5-7 bucks vs Denso 10-12 bucks. so do the math they save avg. $3 per plugs so 12 bucks per car and they make let say 100,000 car/sold. $12*100,000=$1,200,000. thats better than lottery.

:shock:

I moved up from my stock spark plugs to Denso IK16 plugs. The stock plugs I had were Denso SK16R11 (Denso calls this their "premium" iridium plug). The new spark plugs are much better though. They are the real Denso Iridium IK16s.

what is the difference with the numbers?? like 16/ 18/ IX or whatever other number the spark plugs have??

Higher numbers are colder plugs used in high performance applications, especially for forced induction; Hot enough to maintain self-cleaning operating temperature...cold enough to avoid detonation.

ok so what number should I use if my rolla is just stock??I may change my headers later would I then need to change the plugs again?thanks

Hey, guys, sorry to ask. I need to buy a spark plug socket. Before I buy, can someone tell me is it the 18mm one? I apprecite it.
