Best performance spark plug for gasoline sedan

[PATSYS]

Guys, based on your experience, which spark plug brand/type provides the best performance (better acceleration, fuel economy, power, etc)?

When I asked some mechanics, they only said iridium spark plugs are the best but when I searched Lazada, there so many of them with quite wide price range.

PS. Just based on performance, assuming price is not an issue.

*PATSYS - for which car are you sourcing for plugs? Check your manual and use the suggested spark plug model.

For some turbocharged gas vehicles, it requires a specific type of plug and it is a bit pricey than the usual spark plugs.

If stock setup, follow your user manual. That's the best.

Intake, exhaust, strutbar doesnt count ha.. Considered stock bracket pa rin yun! LOL.

If you've changed compression(via piston, shaved head or block, etc..) or boosted/superchaged your previously NA car. Then, let's talk.....

What does your manual say? Just as what others are saying, just follow the suggested plug.

the "i don't have a manual" syndrome.

i don't understand why sellers do not include the manual with the sale.
binebenta ba nila ito afterward sa olx or ebay?

Honestly just use what's recommended by Toyota and replace it every change oil..

Based on experience, stock 1.3-1.6 cars halos walang itutulong ang more expensive spark plugs.

Even iridiums are not "performance" plugs. Mas matagal lang buhay nya.

I could swear the acceleration got better when I shifted to Iridium vs stock/regular plugs.

Copper has better performance, drawback is longetivity.

Correct. Spark plugs degrade overtime. Even if they say that it can last up to 20,000 kms, i dont use them for that long. Mas mura na naman ang iridium plugs kaysa dati. I just replace them around 5-6t kms

Really? Isn't 5-6T kms too frequent? ...
