NEW YORK (TheStreet) -- How will natural gas benefit from higher oil costs, and how should investors play the move?

TheStreet's Jim Cramer told "Mad Money" Research Director Nicole Urken that diesel prices are unlikely to come down because West Texas Intermediate crude prices have now converged with Brent crude prices. This makes diesel even more expensive to use relative to natural gas.

Cramer added that Cummins' new 12-liter natural gas engine is very significant.

He went on to say that Cummins had the right engine, while Chart Industries has the right equipment. Both stocks made new 52-week highs on Wednesday.

While Clean Energy Fuels and Wescorp Energy are both in the field, Cramer said they are not the correct plays.

Cummins and Chart Industries will be the winners when natural gas becomes heavily adopted in 2014.
