Tweaking Matters

I own the new Bajaj Pulsar 180 DTS-i, which is just five months old. I wish to improve its performance by installing a K&N air-filter and Iridium spark plugs. Is it advisable to go ahead with these modifications?

AAA While you could do such modifications, provided you find a plug rated for the exact same heat range and dimensions as used by your bike, we suggest you simply stick to the stock parts on your bike, as any performance gains realized after putting in the new parts will be marginal, and almost negligible.
