Winter is here and car needed some TLC and letting me know by not starting easily in the morning as well after the work.
Initial task was to check the battery: which was replaced 2 and half yearsago , came clean. Next were spark plugs. Checked Autozone and Advance auto parts and their price for Denso platinum was 3.98 each ( last week paid 2.99 for Bosch platinum )
Order through Amazon and the price was 2.49 each for Denso (4504) PK20TT Platinum TT Spark Plug, Pack of 1.
When the delivery was made it comes with pack of 4 in a box.  
Check it out : it fits many cars ( Accord and Camry )
