Did anyone used Denso sprark plugs (Part # S-29A)? I purchased Denso and on the spark plug it doesnt have letter L or T and all 4 plugs have only part #. Does it matter? Current spark plugs are NGK R on FD. Before I Put new one in I just want 2nd opinion.

Thank You

Thank for your help

 

I would only use that plug in the leading position, not trailing. I'd be interested in how the plug works for you if you decide to use it. I bought a few but my testing has crwaled to a hault.

 

Yea i have tried thes plugs. Car sorta went werid on these plugs
Never ran right

 

Lower number (heat range) = leading plugs (lower holes)

I used them and still have a new set. They don't fire as well as the NGK and flood more easily, since they don't have the slits.

 

its working great, i don't see anything wrong.

 

How long have you had them in the car and driveing it.
They may be ok if you are driveing the card hardish.
I found they foul real easy. Good luck with them

 

Silver Bullet has made a superb write up!!!!
I am well impressed

 

you are right , it is really bad spark plugs, i don't recomend it at all. i just went to dealer and got NGK, it fires rightup.

 

Wow, very interesting. What happened TTBullet? Did they foul for you too? I'd be very interested to see some pics.

I'm using BRISK plugs right now. So far I have never used anything so good. I haven't tried the Rx-8 or snowmobile plugs yet though.
