after i did my tune up my check engine light turn on, so i went to my nearest autoparts and they let me use the scanner and i find out that in the cylinder 1 2 and 3 are misfire so that because the spark plugs right?well this is what i think because before it was fine.
Now my question is where is the best place to buy the spark plugs because the ones i bought in carquest autoparts are not good, or maybe it can be the brand, so please give me some ideas

 

i got my NGK Iridium plugs off of ebay...

 

go for NGK they are a bit pricey but there worth it, shop around online first

 

I got mine at autozone and they have been working just fine. If you want the best quality then look online.

 

thank you guys !!!!!

 

the TL likes NGK Platinum (old style) or NGK Iridium (new style used on gen3 and can be used retro)

NGK Iridium `IX` is good if they have them for your year- otherwise use straight Iridium

NGK beats Denso, the only other approved brand to use, in price and lifespan .
Get the acdelco-bosch- whoever plugs that azone sold you OUT!!! and install the right ones

just under 7 bucks each whereever you shop- I use local parts stores so they are still there when I need them for my other cars parts~
50 bucks for plugs you say!?!- yes and they will last another strong 60,000 miles- thats cheap in the long run

 

wots the spark plug gap on NGK BKR6E-N11 SPARK PLUG ?
